What is deposition?
earth material carried by moving water eventually stops moving and settles out
100

Which factor causes particles of earth material (pebbles, gravel, sand, clay) to settle sooner when they are traveling down a river? a. large particle size b. a steep slope c. water that moved quickly d. a large amount of flowing water

a. large particle size

100

When acid rain changes the minerals in a rock, is this an example of physical or chemical weathering?

Chemical

100

True or False: Is soil the same in every location around the world?

False

200

What is erosion?

the movement of pieces of weathered rock by water or wind

200

What is happening when pieces of rock are blown away by the wind? a. weathering b. erosion c. deposition

b. erosion

200
What is physical weathering?
When rocks break up as a result of physical forces
200

Hummus is a. the water in soil that makes it moist b. the dead plant and animal material in soil c. the name for the smallest pieces of earth materials in soil d. the layers of different earth materials that form soil

b. the dead plant and animal material in soil

300

A river pours into the ocean.  Earth materials are deposited over a wide area. Which landform is likely to form? a. valley b. delta c. alluvial fan d. mountain

b. delta

300

What would describe this:  pieces of rock are carried by water and they settle in a new location. a. weathering b. erosion c. deposition

c. deposition

300
What is chemical weathering?
Water or acids that dissolve the minerals in a rock
300

How does soil form?

weathered rock and hummus that has been broken into small pieces and is carried downstream and mixes together.

400

Most landforms take a long time to change. Which answer describes a way landforms change rapidly? a. erosion b. deposition c. earthquakes d. freezing water

500
Water flows fastest from the top of mountains because: a. it has the most water b. it has a steep slope c. it has the longest distance to flow
B. it has a steep slope
500

Which type of rock forms when deposition causes layers of sediments and organic material (humus) to layer on top of one another and cement together?

Sedimentary

500

Physical and chemical weathering are both processes that: a. break earth materials into smaller pieces b. change earth materials into different materials c. use water to move rocks to new locations

a. break earth materials into smaller pieces

500

Which earth material would travel the farthest before deposition occurs? a. pebbles b. sand c. clay

c. clay
