Soil and Rocks: How Is Soil Made?

The video explains the formation of solid rock from lava after a volcanic eruption. It describes how the rock is gradually broken down into soil through natural processes like rain, wind, and ice. Over time, this leads to the formation of new soil, allowing plants to begin growing again in the area.

What natural event led to the formation of the solid rock layer?

• Earthquake

• Flood

• Landslide

• Volcanic eruption

What happens to the lava after it flows across the surface?

• It cools into solid rock

• It remains liquid

• It turns into soil

• It evaporates

Which natural forces contribute to breaking down the rock into smaller pieces?

• Animal activity

• Human intervention

• Rain, wind, and ice

• Sunlight and heat

What is expected to form as the rock breaks down over time?

• New soil

• New water bodies

• New minerals

• New rock

What is beginning to return to the area as new soil forms?
