Vlad1618 [11]

Answer:

The answer is Batholithic intrusions

Explanation:

The Half Dome is an isolated mass suspended within the batholithic intrusions. Developed due to  vertical jointing, exfoliation, and some glacial activity. Steep face of half dome began to take shape as thin slabs of rock b/w parallel vertical joints were loosened by weathering and mass wasting and fell away layer by layer. Tenaya Glacier cleared away exfoliation debris and talus flowing in direction parallel to trend of vertical joints, removed sheets of rock by plucking . Rounded back of Half Dome formed as curved shells of rock exfoliated

<em>4. Amount of food produced in an area </em>

<em></em>

<u>Explanation:</u>

Agriculture yield is important thing in primary sector, it measures the amount of food produced in an area. Before Green revolution, India’s food grain production is not self sufficient to their own people, so India plan to launch the Green revolution. They approach the Norman Borlaug for implement the green revolution who is the Father of Green revolution. Then, India concentrate on High yielded variety (HYV) seeds, fertilisers subsidy, sufficient drainage for crops and so on.

Did oligarchs earn their money in a honest way?
wel
Hey there!
Oligarchy is rule by the rich, usually aristocrats. They indeed did not get their money in an honest way. In most oligarchies, they made laws that benefitted themselves, like unfair tax and odd charges. A common outcome of this type of government is making the rich richer and the poor poorer.
Hope this helps!

Which describes the boundary where earthquake activity occurs along rift valleys?
Andreyy89

Answer:

divergent boundary on land

Explanation:

Divergent boundary involves the crustal spreading of two tectonic plates. Divergent boundary is the separation or rifting apart of two plates. Divergent boundary can occur between oceanic plates or continental plates.

Divergent boundary between oceanic plates , the convection currents lift the lithosphere producing a mid oceanic ridge. Extensional forces spreads the lithospheric plate apart causing an in flow of magma from the interior of the earth. The magmatic materials travels through fissure and oceanic ridges to the surface of the ocean floor. The volcanic material/magma later solidifies to form new oceanic crust with the youngest rock closest to the mid oceanic ridge.

Divergent boundary between continental plates , the convection current usually pull the continental plates upward due to the thickness of the continental plates. The continental plates are pulled thin by the extensional forces resulting to fracture. The fracture result into a rift shaped structure. Rift valleys are formed which is a lowland region. The two parts of the continents(lands) that are separated are likely to develop fault on both sides of the rifts. The fractured area along the rift valley is a region prone to earthquakes.

Rift valley are structures found in divergent boundary between continents(land) and are region of earthquakes activities because of movements and fracturing occurrence. The East African rift is an example of this kind of plates boundary.

liq [111]

Answer:

landslide

Explanation:

This question is related to a picture. In the picture you can see that a small town was affected by a landslide located near a steep hill. As the statement reads, it can be a destructive process as not only is the countryside affected by removal of the top earth layer along with all the vegetation in that area, consequence of heavy rainfall or a mayor earthquake or shift in landmass, but it also turns into a constructive process as at the bottom of the hill, where the landslide or mud accumulates, the debris forms a new layer over the old and it is then seen as constructive.
