Weathering of Rocks by Temperature Change

The video tutorial explains how rocks can be weathered by temperature changes. It describes the process where rainwater seeps into rock cracks, freezes, and expands, causing the rock to crack over time. A simple home experiment is suggested to demonstrate this concept using a water bottle in a freezer. The video concludes with a recap of the weathering process.

What is the initial question posed about rocks in the video?

• How do rocks move?

• What are the types of rocks?

• How can rocks be formed?

• How can rocks be weathered by temperature change?

What happens to rainwater that enters the cracks of rocks?

• It stays in the cracks and freezes at night.

• It evaporates immediately.

• It turns into steam.

• It causes the rock to melt.

What is the result of repeated freezing and thawing of water in rock cracks?

• The rock becomes smoother.

• The rock grows larger.

• The rock cracks and breaks.

• The rock changes color.

How can you demonstrate the expansion of water when it freezes at home?

• By shaking a bottle of water.

• By leaving water in the sun.

• By placing a bottle of water in the freezer.

• By boiling water in a pot.

What happens to the water inside the bottle when it freezes?

• It stays the same size.

• It shrinks and takes up less space.

• It evaporates.

• It expands and becomes larger than the container.

Why is the home experiment with a water bottle considered cool?

• Because it shows how water can boil.

• Because it demonstrates the concept of expansion when water freezes.

• Because it makes the water taste better.

• Because it changes the color of the water.
