What was the slave trade and why was it important?

Answers

The slave trade was the centuries-long practice of forcibly transporting African people and other peoples from their homelands to be sold as slaves in the Americas, Europe, and other parts of the world.

The slave trade was extremely important to the economic development of the Western world, particularly in the early colonial period, when slave labor was used to produce crops and goods for export.

This labor allowed for the rapid expansion of the plantation economies of the West Indies and the American South, and also provided an important source of income for the European powers involved in the slave trade.

What are 5 cons to a command economy?

AND

PLEASE MARK ME AS BRAINLIEST

It restricts freedom.

It may ignore societal needs.

It slows down innovative developments.

It causes black markets to explode.

It offers no competition.

Explanation:

1. It restricts freedom.

Due to the fact that this type of economic system is tied to communist countries, it is no surprise that it also takes the freedom away from the people and puts full control in the hands of the government alone. People can not choose their careers based on their skills and interests; rather, it is based upon what the government forces them to do. All jobs are aligned with needs at a time, and people have little freedom of choice. This major downside to a command economy can lead to discontented citizens.

2. It may ignore societal needs.

Command economy often ignores the needs of the society for its betterment. Workers will not be given the options on where they can work or where they can move.

3. It slows down innovative developments.

Unlike a free market that encourages change and innovation, a command economy does not offer this advantage. Since the government controls the market, it does not make innovation a priority or does not encourage it all in all. This is because it controls all aspects of production and leaves no room for people to make it better, leading to a workforce that is less motivated to create higher-quality products or services.

4. It causes black markets to explode.

Because of restrictions by the government, some products and services are not offered in the command economy, so they would be offered on black markets.

5. It offers no competition.

Competition on the market is one of the main forces of improvement, but in a command economy, there is little competition. The government owns all the industries and does not encourage competition or actually exerts effort to eliminate it. The benefits gained from competition are not seen in this type of market.

The sediment load that travels in solution is?

a. dissolved load.
b. flow load.
c. suspended load.
d. bed load.
e. saltation.

Answers

The sediment load that travels in solution is dissolved load.

For particles to be a dissolved load in a stream, they must be smaller and less dense. Pebbles are about -6 mm in size and pebbles are 6-256 mm  Sand grains are usually 0.125-2 mm in size, but their average density is high

With minerals, this is different because some minerals are larger and some seem. be smaller. Minerals have the property of dissolving during chemical reactions. Unlike dissolved load, the size of the particle transported as suspended load is determined by the velocity of the flow. As the flow moves faster, it can carry larger and larger particles. The larger the particle size the stream can carry, the higher the qualification of the stream.
