the outer portion of a craton, where deformed rocks are covered by sediments, is termed the ________.
The outer portion of a craton, where deformed rocks are covered by sediments, is termed the platform.
The platform refers to the outer, relatively stable portion of a craton. A craton is a large and stable portion of the Earth's continental lithosphere, typically composed of ancient rocks that have undergone significant deformation and tectonic activity in the past.
In the platform region, the deformed rocks of the craton are overlain by relatively flat-lying sediments, which may include layers of sand, mud, or other sedimentary deposits. These sediments accumulate over time, providing a cover or "blanket" over the underlying deformed rocks. The platform is characterized by its relatively gentle topography and is often associated with extensive sedimentary basins and stable geological conditions.

The climatic and rock features that help explain formation of the Grand Canyon are:
(a) glaciers & igneous rock;
(b) tropical rain forest & sand dunes.
(c) river flowing across a rain forest region & this region is sinking below sea level;
(d) river flowing across an arid region & a resistant rock layer;
The river flows across an arid region and a resistant rock layer, which makes it easier to cut through the rock. The resistant rock layer is the Kaibab Limestone, which forms the rim of the canyon. The arid climate in the region allows for rapid erosion by the river, which gradually carves out the canyon.
The climatic and rock features that help explain the formation of the Grand Canyon are a river flowing across an arid region and a resistant rock layer. This is option (d).Explanation:Grand Canyon is a steep-sided canyon that is carved by the Colorado River in Arizona, United States. It is a natural wonder and a famous tourist attraction in the USA. It is believed to be about 6 million years old, but the rock layers that make up the canyon are older than the canyon itself.Climatic conditions and rock formations are two important factors that explain the formation of the Grand Canyon. The rock formations in the area are a mixture of sedimentary rocks such as limestone, sandstone, and shale. These rocks are mostly Paleozoic and Mesozoic in age. The Colorado Plateau was lifted over millions of years due to tectonic activity, and the Colorado River began to flow across the plateau, cutting into the rock layers over time.

The climatic and rock features that help explain the formation of the Grand Canyon are river flowing across an arid region & a resistant rock layer.
The Grand Canyon is a steep-sided canyon located in Arizona, United States. It is formed by the Colorado River and its tributaries, which have exposed a cross-section of layered rock that is over 2 billion years old. The canyon is 277 miles long, up to 18 miles wide, and over a mile deep, making it one of the most significant natural wonders in the world.
The formation of the Grand Canyon is a geological wonder. The Grand Canyon was formed over millions of years by the flow of the Colorado River, which eroded the rock formations.
The climatic and rock features that explain the formation of the Grand Canyon are Rivers flowing across an arid region: The Colorado River is the primary force that carved the Grand Canyon. It flowed across an arid region for millions of years. Due to the low humidity in this region, the rate of erosion was much slower.
Resistant rock layer: The Grand Canyon was formed due to the layers of rocks exposed over millions of years. The rocks were eroded differently, with some eroding more rapidly than others.
The Grand Canyon was formed due to the erosion of the softer rock, leaving behind the harder and more resistant rock layers. These resistant layers formed the steep walls of the canyon.
Climatic features: The arid climate of the Grand Canyon region helped in the formation of the canyon. The hot and dry climate of the area led to the formation of deep gullies and trenches that were then carved deeper by the Colorado River. Additionally, seasonal rainfall and snowmelt caused flash floods that deepened the canyon.
So, the climatic and rock features that help explain the formation of the Grand Canyon are rivers flowing across an arid region and a resistant rock layer.

Sedimentary sequences are blankets of marine sediment that reflect past environmental conditions.
Sedimentary sequences refer to layers of sedimentary rock that have been deposited over time. These sequences provide valuable information about past environmental conditions and the geological history of an area. Sedimentary sequences are formed as sediments, such as sand, silt, and clay, accumulate and are eventually lithified into rock. These sediments can come from various sources, including erosion of land, deposition by rivers, and accumulation in marine environments.
By examining the composition, structure, and fossils within sedimentary sequences, scientists can gain insights into past climates, sea levels, and the evolution of life forms. The phrase "are reflected by blankets of marine sediment" emphasizes that marine sediments, which contribute to sedimentary sequences, provide evidence of past environments and geological processes.

c. Subsistence farming
d. Commercial farming
The correct option is B, The predominant land use in the tropical rainforest is typically Ranching or herding, specifically for cattle.
A rainforest is a lush, dense ecosystem characterized by a high amount of rainfall and abundant biodiversity. It is typically found in tropical regions near the equator, where temperatures are warm and humid. Rainforests are teeming with a wide variety of plant and animal species, many of which are unique and found nowhere else on Earth. The dense canopy of trees in rainforests forms a continuous cover that blocks sunlight from reaching the forest floor, creating a dark and humid environment below.
This unique structure supports a complex web of interdependencies, where countless species rely on each other for survival. Rainforests are often referred to as the "lungs of the Earth" because they play a vital role in producing oxygen and regulating the climate by absorbing carbon dioxide. Unfortunately, rainforests are under significant threat due to deforestation, primarily driven by human activities such as logging, agriculture, and mining. Efforts to protect and conserve rainforests are crucial to preserve their incredible biodiversity and maintain the ecological balance of our planet.

acid rain is the direct result of acid released by burning fossil fuels. please select the best answer from the choices provided. TRUE/FALSE
Acid rain is the direct result of acid released by burning fossil fuels. This statement is true.
When fossil fuels, including coal/oil, are burnt to produce energy, they release harmful chemicals into the atmosphere including nitrogen oxides(NOx) and sulfur dioxide([tex]SO_{2}[/tex]).
These gases when released into the atmosphere, undergo chemical reactions by combining with oxygen and water vapor present in the atmosphere to form sulfuric acid([tex]H_{2} SO_{4}[/tex]) and nitric acid ([tex]HNO_{3}[/tex]).
These acidic compounds further mix with rainwater, and form acid rain when it precipitates into the earth's atmosphere.
However, it is also important to note that other activities including industrial processes and burning of biomass also play a role in the formation of acid rain.

https://brainly.com/question/11543614
Yes, the above statement is true. Acid rain is indeed the direct result of acid released by burning fossil fuels.
When fossil fuels such as coal, oil, and gas are burned for energy production, they release pollutants, including sulfur dioxide (SO2) and nitrogen oxides (NOx). These pollutants can react with water vapor and other atmospheric components to form sulfuric acid and nitric acid, respectively. These acids then mix with rainwater, snow, or fog, resulting in acid rain.
The combustion of fossil fuels in industrial processes, power plants, and vehicles is a significant source of the pollutants responsible for acid rain. This phenomenon has detrimental effects on ecosystems, vegetation, aquatic life, and infrastructure, making it a significant environmental concern. Efforts to reduce emissions of sulfur dioxide and nitrogen oxides have been made to mitigate the occurrence of acid rain and its impacts.

a) 1 and 2 only
b) 2, 3, and 4 only
c) 1, 3, and 4 only
d) 3 and 4 only
e) 1, 2, 3, and 4
Answer: (3) Speed of propagation and (4) Direction of propagation.
The following four quantities change as the light enters the water: (1) wavelength, (3) speed of propagation, and (4) direction of propagation. The answer is (c) 1, 3, and 4 only.
When a ray of light passes from air into water, the speed of propagation of the wave will decrease. The reason for this is that light travels slower in water than it does in air. This change in speed will result in a change in the direction of the wave's propagation, meaning that it will be refracted.
The angle at which the light is refracted depends on the angle of incidence and the refractive index of the two media involved. However, the frequency of the light does not change when it enters water from air. This means that the energy of the wave remains the same, despite the decrease in speed.
Finally, the wavelength of the wave will change when it enters the water, since the speed of propagation will be different in the two media. The wavelength will decrease as the wave enters the water, since the speed of propagation is lower in water than it is in air.

Which has greater competence? a. a small mountain stream b. the Mississippi River
The Mississippi River has greater competence compared to a small mountain stream. Competence refers to a river's ability to transport sediment, and it is influenced by factors such as water velocity, channel shape, and sediment load.
The Mississippi River, being one of the largest rivers in the world, carries a significant sediment load and has a higher water velocity, enabling it to transport larger and more diverse particles over greater distances. In contrast, a small mountain stream typically has lower water velocity and a smaller sediment load, resulting in lower competence and a limited ability to transport larger or heavier sediment particles.
The Mississippi River receives sediment from various sources, including its tributaries and erosion from its surrounding landscapes. This sediment includes a wide range of particle sizes, from fine silt and clay to coarser sand and gravel. Overall, the Mississippi River's size, flow velocity, and sediment load give it a significantly greater competence compared to small mountain stream.

Caucasus region; and harsh and often life-threatening prison conditions. Arbitrary
detention and politically motivated imprisonments were problems. The government
controlled many media outlets and infringed on freedoms of speech and
expression, pressured major independent media outlets to abstain from critical
coverage, and harassed and intimidated some journalists into practicing self-
censorship. The Internet remained by and large free and provided citizens access to
