When calcite in limestone reacted with "acid rain" during our experiment, what type of weathering was this?
When water fills cracks in rocks and freezes, it can break rocks apart. What happens to the water when it freezes?
The water expands when it freezes
What do physical and chemical weathering have in common?
They both break earth material into smaller pieces
How do physical and chemical weathering differ?
Chemical weathering produces new material (like the crystals we saw in the petri dish) and physical weathering does not.
What is abrasion?
When rocks bang against each other and break, creating smooth, round rocks.
Some processes change landforms slowly, while others change them very quickly. Would tree roots be an example of a quick change or a slow change?
Some processes change landforms slowly, while others change them very quickly. Would a flash flood be an example of a quick change or a slow change?
What types of materials make up soil?
pebbles, sand, water, humus, clay, gravel, air
What is deposition?
Deposition begins when erosion stops; it is when the moving particles fall out of the water or wind and settle on a new surface.
What is erosion?
the carrying away of weathered earth materials by water, wind, or ice
