Weathering and Erosion.

๐ŸŽฏ Your mission

Understand the idea. Then look for it everywhere.

โšก The twist

The slowest changes are the biggest ones.

๐Ÿคฏ

Mind = Blown

๐Ÿชจ Every grain of sand on every beach used to be a mountain.

๐Ÿ”ฎ

Make a hypothesis first

What You'll Learn

Landslides occur when slopes become unstable due to heavy rain, earthquakes, or human activity. Gravity pulls loose rock and soil downhill, sometimes with devastating speed.

Key Words

  • landform
  • soil

Steps

Step 1 โ€” Read

Study the diagram and label the parts you recognize.

Step 2 โ€” Do

Step 3 โ€” Observe

Watch carefully for any changes and note the time.

Step 4 โ€” Record

Create a data table to organize your measurements.
