layers of the geosphere
review
100
gases in the atmosphere that absorb and reradiate thermal energy from the sun
What are greenhouse gases?
100
How does carbon move from the atmosphere into the hydrosphere?
It is absorbed into the water.
100
How are rocks and minerals related?
Rocks are made of minerals.
100
Which layer of the geosphere is most dense?
Inner core
100
Name four interactions among the Earth systems.
water cycle, rock cycle, carbon cycle, phosphorus cycle.
200
a series of processes that move phosphorus among Earth systems
What is the phosphorus cycle?
200
What is the form of carbon in the atmosphere?
gas
200
Name 1 characteristic of a mineral
1. naturally occurring 2. inorganic 3. solid 4. definite chemical composition 5. crystal structure
200
Which layer of the geosphere is liquid iron?
the outer core
200
Which Earth system hold the smallest amount of carbon?
the atmosphere
300
the tendency of minerals to break along irregular lines
What is fracture?
300
Name 1 way humans impact the carbon cycle.
Cellular respiration deforestation burning fossil fuels
300
Name a property used to identify an unknown mineral.
luster, streak, hardness, cleavage, and fracture.
300
Which layer is part of the asthenosphere?
lower mantle
300
Name the Earth Systems
atmosphere biosphere geosphere hydrosphere
400
the way a mineral's surface reflects light
What is luster?
400
How does the amount of materials change as they move throughout the Earth systems?
The materials may change state, but the amount remain the same.
400
Which type of weather changes the make-up of rock.
chemical weathering
400
Which layer is thin and brittle?
crust
400
This type of rock is formed when magma cools.
igneous rock
500
partially melted layer of the mantle
What is the asthenosphere?
500
This type of rock is formed when sediment is exposed to high temperatures and/or high pressure.
What is metamorphic rock?
500
Which soil horizon is most fertile and why?
The A-horizon is most fertile because it contains organic material such as animal decay and wastes.
500
Why is the geosphere layered the way it is layered?
Gravity pulled the dense materials to the center of the geosphere.
500
What happens when animals on Earth die and begin to decay?
They release phosphorus into the geosphere.
