Answer:

When plates move away from each other, the space between them gets filled with material, which rises to the surface, cools and forms mid-oceanic ridges. The Pacific Ocean is growing wider by about 18 cm per year as the plates diverge and the mid-oceanic ridge is built up. Where plates come into contact, energy is released. Plates sliding past each other cause friction and heat. Subducting plates melt into the mantle, and diverging plates create new crust material. Subducting plates, where one tectonic plate is being driven under another, are associated with volcanoes and earthquakes.

When Alfred Wegener first proposed the idea of continental drift (the precursor idea to plate tectonic theory), it didn’t quite explain the full story. While he correctly showed that Africa and South America fitted together, his model wasn’t able to explain the violent forces that occur around the Earth’s crust. It wasn’t until the 1960s that a full explanation began to develop – the theory of plate tectonics.

The person who suggested that the continents were once a supercontinent, called Pangaea, but slowly drifted apart was Albert Ein

Alinara [238K]

The correct answer is: Alfred Wegener. Alfred Wegener (1880-1930) was a German polar researcher, meteorologist and geophysicist, and a first person who suggested that the continents were once a supercontinent called Pangaea, but slowly drifted apart. While he was still alive, Wegener was best-known for his achievements in meteorology and as a pioneer of polar research, but today he is most remembered as the creator of the theory of the continental drift. This idea was controversial in the beginning, but today, scientist believe that Pangaea really existed during the late Paleozoic and early Mesozoic eras.

the property of the atmosphere that describes weather circulating air motions will be strong or weak is called

monitta

Answer:

Stability

Explanation:

Stability (or atmospheric conditions) describes the tendency of the air either with rise and generate storms (destabilization) or resist vertical motion (stability).

As is valid of a balloon, the best way to explain how equilibrium functions is to consider a parcel of air getting a thin , lightweight cover that helps it to stretch but prohibits the air within from interacting with the surrounding atmosphere.

In a market economy, what determines for whom goods are produded?

Galina-37 [17]

Answer:

C. supply and demand

Explanation:

In the system of the market economy, the decisions about economic processes are based on the of the people (how much they need and buy something) and the needs of the supply (needs for natural resources, goods, and things which can be bought).

A market economy also means the pricing of the goods is based on the demand for them. If products are not in demand and bought by the customers, it’s the price and supply goes down. Once the demand for the product grows, the profit is made.

The final goal is the price which is equilibrium, meaning goods are supplied exactly by the demand and with the fixed price that makes the process possible. This equilibrium should also provide the profit for the supplier.
