PLS HELPP
Answer: (sorry I need to get free answers ad free)
Explanation:
Rock Layer E is 250,000 years old. Rock Layer C is 200,000 years old. Rock layer C has not undergone radioactive decay and has 18 radioactive isotopes. The half-life is 50,000 years. Rock Layer E has undergone radioactive decay ONCE, how many daughter and parent isotopes are present in layer E?
Answer:
Explanation:
By definition, after a radio active decay, a parent isotope will create a daughter isotope.
Layer C is exactly one half-life from Layer E at 50000 years. So half of the original parent isotopes from Layer E would have decayed to form daughter isotopes. As C has 18 radioactive isotopes together, E should have 6 daughter and 6 parent isotopes.
Answer:
Explanation:
Rock Layer E is 250,000 years old. Rock Layer C is 200,000 years old. So the two layers are off by 50,000 years; equal to one half-life.
As Rock Layer E has undergone radioactive decay ONCE, each parent isotope forms one daughter isotope after the decay.
Rock layer C has not undergone radioactive decay and has 18 radioactive isotopes. So that represents an equal number of parent and daughter isotopes, i.e. 9 parent and 9 daughter isotopes.
So there are 9 parent and 0 daughter isotopes in layer E.

What special physical property of the upper mantle supports the Theory of Plate Tectonics?
Lithosphere
The lithosphere is the solid, outer part of the Earth, extending to a depth of about 100 kilometers (62 miles). The lithosphere includes both the crust and the brittle upper portion of the mantle. The lithosphere is both the coolest and the most rigid of Earth’s layers.
One environmental consequence of the large-scale cultivation of cotton in the South was widespread soil exhaustion caused by decades of farming widespread soil exhaustion caused by decades of farming drought caused by overuse of river water to irrigate farmland drought caused by overuse of river water to irrigate farmland air pollution cause by the use of cotton gins air pollution cause by the use of cotton gins widespread water contamination caused by fertilizer runoff
Answer:
Widespread soil exhaustion caused by decades of farming.
Explanation:
The agricultural lands of the south were extensively exploited with intensive cotton cultivation. This cultivation lasted for decades and was developed with agricultural techniques that were not concerned with sustainability. As a result, the southern soil was severely depleted. Soil exhaustion refers to the extreme reduction of organic matter. In the case of southern soils, the intensive use of the soil with cotton planting was the main cause of this exhaustion, however inadequate irrigation practices, mechanization of the soil, deforestation and burning can cause the same effect.
To avoid this, farmers in the south should have adopted practices that are more beneficial to the environment, in addition to promoting crop rotation.

How does river originate from mountain? Describe briefly.
Answer:
Most rivers begin life as a tiny stream running down a mountain slope. They are fed by melting snow and ice, or by rainwater running off the land. The water follows cracks and folds in the land as it flows downhill. Small streams meet and join together, growing larger and larger until the flow can be called a river.Explanation:
