What is physical weathering?
Rocks disappearing into water
Rocks breaking into smaller pieces without changing material
Rocks melting into lava
Soil being carried by wind
Which example shows physical weathering?
Sand blowing across a desert
Water freezing in rock cracks and breaking the rock apart
Soil settling at the bottom of a river
A river carrying rocks downstream
What happens during erosion?
Materials like sand and soil move to a new place
Rocks melt underground
Rocks change color
Rocks break into smaller pieces
Which force can cause erosion?
light
heat
wind
sound
Which example shows erosion?
Wind blowing sand across land
Soil forming from rock
Water freezing in cracks
A rock cracking apart
What happens during deposition?
Materials are dropped in a new location
Materials move quickly
Materials break apart
Rocks turn into soil
When does deposition usually happen in water?
When water freezes
When water disappears
When water slows down
When water speeds up
What is the best evidence that a flood happened?
Warm weather
Dry soil
Clear skies
Rocks and soil left on sidewalks and roads
What happens when rainfall increases?
More erosion and more deposition occur
Nothing changes
Weathering stops
Less erosion happens
What usually happens first?
Flooding
Weathering
Erosion
Deposition
Which shows the correct order of processes?
Erosion → Deposition → Weathering
Erosion → Weathering → Deposition
Weathering → Erosion → Deposition
Deposition → Weathering → Erosion
Ocean waves breaking rocks into smaller pieces is an example of:
Flooding
Erosion
Deposition
Weathering
Water gets into a small crack in a rock. Overnight the temperature drops and the water freezes. What will most likely happen to the rock?
the rock will melt
Nothing will happen
The rock will turn into soil
The rock will crack because the ice expands
A scientist pours water into a crack in a rock. The water freezes overnight. The next day the crack is larger. What caused the change?
The water expanded when it froze
The water evaporated
The rock melted
The rock moved downhill
What is sediment?
Air trapped underground
Soil, sand, and small rocks that can be moved by water or wi
Melted rock
Ice inside rocks
What force pulls water downhill and helps cause erosion?
light
heat
sound
gravity
