pebbles, rock chips and sand
|
|
|
Weathering has several different forms. What are they?
|
abrasion, erosion, depostion
|
|
|
What effects how moving water erodes and deposits sediment?
|
amount of water, speed of water, type of sediment
|
|
|
True or False: Landforms change over time.
|
true
|
|
|
True or False: Weathering is a process in which sediment is carried away by water.
|
false (erosion is that specific process)
|
|
|
True or False: The steeper the slope of the river table, the faster it will erode.
|
True

Factors that can cause change to the Earth's surface are...
|
water, wind, ice, plants, animals, humans, cataclysmic events

|
|
Are all rocks the same hardness? How do you know?
|
No, rocks can be different hardness levels. You can determine if one rock is harder than another rock by rubbing the rocks together. If Rock A causes abrasion on Rock B, then Rock A is harder.
