Describe each type of mountain. Include the type of boundary where they are likely formed and characteristics of each. Folded Mountains: Fault-block Mountains:

Answers

Answer:

Folded mountains are all those originated by movements and collisions of the great plates that form the earth's crust. Fault-block mountains are those that appear from a break in the crust, a fact that causes the rock blocks to move up and down and form elevations.

Explanation:

The parallel movement of the earth's crust leads to the appearance of Folded Mountains. According to this theory, Folded Mountains originate from the collision between two tectonic plates. Some of these plates are huge and can support and carry entire continents. When two plates collide, the denser one gets under the other, and this causes the sediments deposited in the basin or geosyncline that separated them to fold up. The large folds formed in the compressed sediment can break apart and form mountains.  Fault-block Mountains are related to normal wide-angle faults that gradually decrease in dip with depth. Most of the Fault-block Mountains form in response to a large uplift.

3. Explain how the Gulf Stream (a warm ocean current) effects the climate of Northern Europe.

Answers

Answer:

These currents transfer heat from the tropics to the polar regions, influencing local and global climate..

The warm Gulf Stream originating in the tropical Caribbean, for instance, carries about 150 times more water than the Amazon River. The current moves along the U.S. East Coast across the Atlantic Ocean towards Europe ...The heat from the Gulf Stream keeps much of Northern Europe significantly warmer than other places equally as far north.

Answer:

The Gulf Stream, located in the north Atlantic Ocean, has an important effect on climate, transportation by sea, and the circulation of nutrients and waste in the ocean. It works together with the North Atlantic Drift to bring warm air from equatorial regions across Europe. This changes Europe’s climate by providing mild temperatures and more rain. As a result, farmers can grow more crops, and fewer freezing temperatures damage goods.
