Earth's Spheres
What is an example of each sphere
geosphere: rock
hydrosphere: lake
cryosphere: glacier
atmosphere: air
biosphere: people
Animals cause what type of weathering
physical
What shapes shorelines
waves
currents
How can wind shape earth
abraded rock
desert pavement
dunes
loess
What are the 3 main soil horizons
A, B, and C
What is an example of earth's spheres interacting
Solar energy from warms the atmosphere, creating winds. The winds then cause tides in the hydrosphere
Is weathering a quick or long process
long
What can cause the discharge of a stream to increase
major storm occurs
warm weather rapidly melts snow
What kinds of ice shape earth
flowing ice
alpine glaciers
continental glaciers
What are some properties of soil
texture, color, chemistry, pore space
What is the earth's energy budget.
The energy going into a system vs. the energy leaving the system
What can cause an abrasion
wind, water, gravity
Where is a wave cut platform formed compared to a sea cliff. ( at the top or at the bottom)
At the bottom
How can gravity shape earth
slow mass movement
rapid mass movement
What causes soil to form
weathering of parent rock
decomposition and mixing by living things
Compare and Contrast the hydrosphere and cryosphere
Both: made of water
Hydrosphere: liquid water
Cryosphere: Solid (frozen) water
What causes chemical changes
react with oxygen
react acid precipitation
React with acids in ground water
react with acids in living things
What are two coastal landform made by erosion
sea cliffs and wave cut platforms
sea caves, arches, and stacks
What is an example of a rapid mass movement
rockfall
landslide
mudflow
Which would grow a plant faster: a warm, flat area with lots of animals
or
a cold, steep area with no animals
warm, flat area
What can disturb earths energy budget
Greenhouse gases and Melting polar ice caps
What are the agents of physical change
temp. change
pressure change
animals
Wind/water/gravity
plant growth
What factors relate to a streams ability to erode material
gradient
load
discharge
What landforms are made by alpine glaciers
arete
cirque
horn
u-shaped valley
What factors determine how long it takes for soil to form
rock type
climate
topography
plants/animals
