Slow or Quick Changes
Soil
Weathering
100

The breaking down of rock on Earth's surface into smaller pieces.

DAILY DOUBLE

What is weathering?

100
Wind and water can carry sand and small pieces of rock to new locations. True or False
What is True?
100
Volcanoes change Earth's surface...(slowly/quickly)
What is quickly?
100

This horizon is a solid slab of rock, in which no life is present.

What is bedrock (or R horizon)?

100
Small pieces that break off of rocks.
What is sediments?
200
Mountains and other surface features of the land.
What are landforms?
200
When rainwater seeps into cracks in rocks and __________, it expands and causes the rock to split apart.
What is freezes?
200
Weathering changes Earth's surface...(slowly/quickly)
What is slowly?
200

This has minerals, humus, worms, air, and water.

What is the composition of soil?

200

When a river meets an ocean, the water direction/speed changes and causes this landform to be built by deposition.

What is a delta?

300
The process by which weathered rock is picked up and moved to a new place.
What is erosion?
300
Weathering over long periods of time breaks rock into ____________ pieces. (larger or smaller)
What is smaller?
300
Erosion can change the shape of the land faster than a volcano can. True or False.
What is False?
300

Soil contains minerals, organic material, water, air, worms that can support the growth of plants. True or false?

What is the importance of soil?

300

Water seeps into cracks and pores in the rock. As water freezes into ice, it expands, pushing the rock apart and forming new cracks. Over time, the solid rock is shattered into smaller pieces.

What is frost wedging? (mechanical weathering)

400

These decomposers aid in soil health by creating tunnels for water to move around. Their castings also add beneficial nutrients to the soil.

What are worms?

400
Fast flowing rivers can pick up and carry rocks (far/short) distances.
What is far?
400

Water can weather rock by: A. eroding soil B. by freezing and melting

DAILY DOUBLE


What is freezing and melting?

400

The material in which all soil and horizons above it is formed.

Bedrock


400

A glacier is slowly-moving river of ice. As the ice moves over the surface, it drags rocks along the bottom, which grind down the rocks below.

What is abrasion? (mechanical weathering)

500

When iron in rocks is exposed to air and water, it undergoes a chemical reaction. 

What is oxidation? (Chemical Weathering)

500

All of the following are forces that change landforms EXCEPT: a. wind b. moving water c. glaciers d. physical features

What is physical features?

500
Landslides are quick changes to the land. They can be caused by: A. magma and rain B. gravity and rain
What is gravity and rain?
500

List all layers of Soil Horizon Profile in order from top to bottom.

O, A, B, C, R

Organic Layer, A Horizon, B Horizon, C Horizon, R Horizon

500

Naturally occurring, inorganic solid, with a crystal structure and definite chemical composition.

What is a mineral?
