Answer:
Volcanic rock (often shortened to volcanics in scientific contexts) is a rock formed from lava erupted from a volcano. ... Volcanic rocks and sediment that form from magma erupted into the air are called "volcaniclastics," and these are technically sedimentary rocks.
Explanation:
Polar regions
Temperate forests
Tropical rain forests
Polar regions do not have many animals.
Temperate forests have a few animals, not too many
Tropical rain forests have many different animals and many plants. Therefore, it has the most biodiversity
Answer:

2. Cementation occurs when mineral-bearing water circulates among the grains, hardens, and cements the sediment grains together. This process is most effective when lithifying sand and gravel-sized sediments.
