Define It!
The process by which small pieces of rock and soil are moved.
What is:
EROSION
WEATHERING a natural process. T or F
True
Erosion is always caused by humans. T or F
False
The sphere of Earth that contains Mount Washington.
What is the geosphere?
Photosynthesis
What is the biosphere - atmosphere (or hydrosphere)?
When the earth's surface is broken down into smaller pieces.
What is:
WEATHERING
What are the different types of weathering?
What are:
a. Physical Weathering
b. Chemical Weathering
Erosion means sediment stays in same place, just gets smaller
What is:
False
This sphere contains the most species of organisms in the world.
What is the biosphere?
Logging
What is biosphere-biosphere?
Heat capacity of water
What is the ability of water to absorb heat without increasing temperature?
The speed at which weathering occurs.
What is slow?
Can erosion happen before weathering?
No, weathering must occur first, then the broken pieces are carried away.
This sphere is responsible for keeping Earth's temperature regulated.
What is the hydrosphere?
Melting glaciers
What is hydrosphere-atmosphere?
Small, solid pieces of material that come from rocks or living things
What is:
Sediment
This weathering changes the molecular make-up of the rock.
What is chemical?
This sphere creates wind.
What is the atmosphere?
This sphere contains carbon dioxide, a greenhouse gas the keeps Earth warm.
What is the atmosphere?
Soil runoff
What is the hydrosphere-geosphere?
Water that moves across the land surface and into streams and rivers
What is:
Runnoff
Five agents of mechanical weathering.
What are:
a. Water
b. Air
c. Ice wedging
d. plant root pry
e. animal burrowing
THREE agents of erosion are:
What is:
1. Wind
2. Ice (glaciers)
3. Water
4. Gravity
5. Animals
This sphere contains the cryosphere.
What is the hydrosphere?
The Grand Canyon
What is the hydrosphere-geosphere?
