Over the past 10 years, Country A has needed fewer and fewer farmers even though its population is growing and its economy is do

klasskru [66]

Answer:

C. Improved technology in agriculture means it takes fewer farmers to produce the food the country needs.

Explanation:

The development of farming equipment has caused a reduction in the need for manual labor. Machines such as combine harvesters allow for vast amounts of farm work to completed in a short period. It also helps with extensive commercial farming which means there are bigger farms and fewer farmers. The Green Revolution in the mid-1900s saw the development of high yield variety crops that were stronger and more reliable. While more fertilizer and water is needed, people are not.

How would the weathering of a bear mountain peak differ from the weathering of bedrock under a forest?

monitta

The weathering of the mountain peak will be mostly through the influence of the wind, water, and ice, while the bedrock under a forest will be influenced by the plants.

Explanation:

The weathering is a process that occurs everywhere in the world, on the surface and close to the surface of the planet. This process is basically the breaking up of particles from larger masses of rocks. Which type of weathering will be dominant at a particular place depends n multiple factors, such as:

topography
vegetation
climate
presence/absence of water

A bear mountain peak will be exposed to strong winds. Also, the lack of vegetation will enable the water from the rainfall to have big influence, while in the colder months the formation of ice will contribute to significant weathering. On the other side, the bedrock under a forest will have minimal influence from wind, water, and ice, as the vegetation provides protection. The vegetation on the other hand, with its roots, as well as with the decomposition will manage to weather the rocks, both on the surface and inside the ground.

Answer:

There are several tectonic provinces collectively called as crystalline providences.

Explanation:

The geology of Appalachians consists of Blue Ridge, Piedmont, Adirondack, and the New England providences. They are known as Crystalline provinces.

The sinking of the oceans continued about 270 million year ago due to which a huge mass of rocks was pushed westwards along the margins of North America and piled up to form the mountains.
