What happens to the warm, less dense material inside earth? moves sideways remains stationary rises towards the crust sinks towards the outer core

Rises towards the crust

Explanation:

In the Earth's crust, movement of materials is as a result of thermal convection that is occurring within the earth's crust.

When thermal convection occurs, the warm, less dense material inside earth rises towards the crust , while the cool and denser material with sink towards the outer core.

This rising of warm, dense material and sinking of cool, denser material causes a shift in the tectonic plates and stimulates the release of a convection current.

answer: grassland biomes are closer to the equator and receive more rain.

grasslands are biomes that are dominated by grasses rather shrubs and trees. savanna are biomes that exhibit grasses, shrubs and small tree as vegetation. grasslands are located near the equator of the earth. these are found in north america. savanna biomes are found in africa, south america, australia and india. grassland exhibit moderate climatic conditions, it receives   amount of rainfall higher than savanna.   therefore, savanna exhibit dry and hot climatic conditions.
