What's It Mean?
The breaking down of rock on Earth's surface into smaller pieces.
What is weathering?
True or False, Plants can only cause rocks to weather mechanically.
What is False?
True or false, Chemical weathering can produce new rocks as it breaks down the rock.
What is True?
The difference between weathering and erosion is: A. weathering causes a quick change in landforms and erosion causes a slow change in landforms. B. weathering breaks rocks into sediments and erosion moves sediment from one place to another.
What is B?
Weathering over long periods of time breaks rock into ____________ pieces. (larger or smaller)
What is smaller?
Mountains, volcanoes, plains and other surface features of the land.
What are landforms?
Animals like chipmunks can burrow in the ground and loosen and break apart rocks in the soil.
What are animal actions?
True or false, Living Organisms can produce weak acids that slowly dissolve rock.
What is True?
True or false, Abrasion can mechanically and chemically weather rocks.
What is False?
True or false, cold and dry climate weathers rock faster than hot and wet climate.
What is a false?
The process by which weathered rock is picked up and moved to a new place.
What is erosion?
Physically breaking down of rocks.
What is Mechanical Weathering?
Pollution in the air can react with water vapor in clouds.
What is acid rain?
Name a difference between weathering and erosion.
What is weathering makes things smaller, and erosion moves it?
Rocks full of tiny, connected air spaces that allow water to seep through it.
What is a Permeable?
When rainwater seeps into cracks in rocks and freezes, it expands and causes the rock to split apart.
What is frost wedging?
Pressure on the rock is reduced and causes the outside of the rock to crack and flake off.
What is release of pressure?
Iron combines with oxygen and water to weather rocks.
What is oxidation?
The difference between physical and chemical weathering is: A. Physical weathering just breaks things apart and chemical weathering changes the rocks forever. B. Physical weathering breaks things apart and chemical weathering burns rocks with chemicals.
What is A?
Two factors that determine the rate at which rocks weather.
What are type of rock and climate?
A process in which a solid becomes part of a liquid to form a solution (fluid).
What is a Dissolving?
Sand and other rock particles carried by wind, water, or ice can wear away rock surfaces.
What is abrasion?
When ________ dissolved in water and dripped down from ceiling of caves to form stalagmites.
What is carbon dioxide?
How can water mechanically and chemically weather rocks?
What is water carrying small rocks to abrade rocks and carrying chemicals to dissolve rocks.
River current carving rocks at the bottom, making it smooth.
What is mechanical weather/abrasion?
