The slopes of most cinder cones are usually about 30 degrees because that is the angle of repose, which is the slope at which the loose cinder can stand in equilibrium.
The cinder cones vary significantly in height, from just a few meters of height to few hundred meters.
They are numerous around any volcano, and lava can come out of them or may flow below them.
C.sediments transported by wind,water, and ice
A steppe is a large expanse of grasslands and few trees. So the choice of grassland with few trees would be your answer.
Good luck :)
Oceanic and continental plates are colliding.
Explanation:
On the image, we can see an oceanic plate on the left, and a continental plate on the right, moving toward each other and colliding. Because the two plates have different densities, thickness, and elevation, one of the subducts below the other, that being the oceanic plate. As the oceanic plate subducts below the continental plate, it gradually moves down in the mantle layer, getting melted, recycled, and maybe the same material be pushed toward the surface again.
On the plate boundary, convergent in this case, there is intense geological activity. Magma manages to rise through the cracks and gaps, and it forms volcanoes, creating a continental volcanic arc. Also, there are lot of earthquakes at such boundaries, as there is constant adjustment of the crust.
Such boundaries can be found between the:
- Pacific and North American plates
- Pacific and Eurasian plates
- Pacific and Australian plates
- Pacific and Philippine plates
- Nazca and South American plates
- Cocos and North American plate
