Rocks, Rock Cycle, and Weathering

The breakdown of rock and soil is called..

• Deposition

• Weathering

• Erosion

• Physics

How is mechanical weathering different from chemical weathering?

• Chemical weathering happens over a much shorter time frame than mechanical weathering

• Chemical weathering occurs in the tropics; mechanical weathering occurs in temperate climates

• Chemical weathering occurs in the mountains; Mechanical weathering occurs on flat surfaces

• Chemical weathering changes the chemical compositions of materials; mechanical weathering does not.

The breakdown of rocks caused by freezing and thawing is called..

• Mechanical Weatherin

• Chemical Weathering

• Erosion

• Deposition

What types of rocks are formed by weathering?

• Metamorphic rocks

• Igneous rocks

• Sedimentary rocks

• Volcanic rocks

Metamorphism is..

• Where water and wind carry away sediments

• Where chemical reactions change rocks into other substances

• Where intrusive igneous rocks become extrusive igneous rocks

• Where heat and pressure are applied to a rock to change it

Which type of rocks are formed quickly above ground?

• Extrusive Igneous Rocks

• Sedimentary Rocks

• Metamorphic Rocks

• Intrusive Igneous Rocks

1.      Which biome is likely to be most affected by wind erosion?

• Deciduous Forest

• Rain Forest

• Desert

• Grasslands

Oxidation is ..

• The process by which Oxygen helps break down something

• The process of opening up an object to breathe

• A classy way of breathing

• A loss of hydrogen

Carbonic acid is a mixture of ...

• Water and limestone

• Calcite and quartz

• Oxygen and Hydrogen

• Water and Carbon Dioxide

What impact does weathering have on soil formation?

• Chemical weathering adds helpful chemicals to the soil

• Rocks are broken down into smaller pieces, and finally into sediment

• Mechanical weathering adds ice to the soil, which turns into water

• Volcanic eruptions contribute metamorphic rocks to the soil.
