Changes to Earth's Surface
Grade 2 - Science - Challenge Me
Worksheet 1
1Earth event: wind blows loose sand into small dunes. Is this a fast or slow surface change?
2What most directly causes this surface change: a flood spreads mud across a field?
3Which observation is evidence for the change in "a flood spreads mud across a field"?
4Which solution could help with this surface-change problem: waves break pieces from a sandy shore?
5Which sequence best represents a surface change investigation?

About this worksheet
Earth's surface changes in both fast and slow ways. A flood or landslide can change a place quickly, while wind, waves, roots, and running water may reshape land over longer periods. Second graders often think landforms are permanent because many changes are slow compared with a school day. They may also name the event without identifying the evidence that shows what caused it. This worksheet uses short scenarios about rivers, hillsides, dunes, shores, floods, and roots. Students classify fast and slow changes, identify wind or water as a cause, choose observations that count as evidence, and select reasonable ways people can reduce damage. Support versions use clear labels. Challenge versions ask students to connect the process, evidence, and solution. Encourage your child to ask what moved the land material and how quickly the evidence changed.
What your child will learn
Classify fast and slow surface changes
Identify wind, water, roots, and gravity as causes
Use evidence to explain erosion
Choose solutions that reduce land change damage
Worked example
If waves remove sand from a shore over many weeks, that is a slow change caused by moving water.
Common mistake
Assuming land never changes unless the change happens suddenly.
