Changes to Earth's Surface
Grade 2 - Science - On Level

Earth event: a landslide moves soil down a hill after heavy rain. Is this a fast or slow surface change?
- only a weather report
- no surface change
- slow change
- fast change
What most directly causes this surface change: tree roots crack a sidewalk over years?
- the color of the soil
- the name of the town
- classroom light
- growing roots
Which observation is evidence for the change in "waves break pieces from a sandy shore"?
- the field has a name
- the shoreline moves back over time
- the hill has a pretty view
- the sand is a favorite color
Which solution could help with this surface-change problem: wind blows loose sand into small dunes?
- make the wind stronger
- use fences or plants to slow the sand
- ignore all evidence
- add loose soil to every slope
Which sequence best represents a surface change investigation?
- name the map -> ignore the land -> finish
- erase the evidence -> copy the answer -> stop
- observe the surface -> identify the cause -> plan a response
- predict first -> refuse data -> change the question
Earth event: waves break pieces from a sandy shore. Is this a fast or slow surface change?
- fast change
- slow change
- only a weather report
- no surface change
What most directly causes this surface change: a flood spreads mud across a field?
- the color of the soil
- flood water
- classroom light
- a paper map
Which observation is evidence for the change in "a river carries sand from one bank to another"?
- the field has a name
- the sand is a favorite color
- the student guessed first
- the bank is worn away over many days
Which solution could help with this surface-change problem: a flood spreads mud across a field?
- add loose soil to every slope
- remove every observation
- make the wind stronger
- build safe drainage paths
Which sequence best represents a surface change investigation?
- name the map -> ignore the land -> finish
- observe the surface -> identify the cause -> plan a response
- erase the evidence -> copy the answer -> stop
- choose a favorite rock -> stop observing -> guess
