Glaciers
100
The outermost layer of Earth
What is the crust
100
The Mid-Ocean ridge is formed by this
What is Sea-Floor Spreading
100
Within the next 100 million years, the Great Rift Valley in Africa will most likely become what
What is divergent boundary
100
As the speed of the wind increases, the amount of soil eroded will?
What is increase
100
This shape valley provides the best evidence of a glacier
What is U-shaped
200
The layer of the Earth where there are convection currents.
What is the mantle
200
This increases the size of the plates
What is sea-floor spreading
200
The dependent variable from the soil lab
What is the rate of water draining through the soil
200
One way to reduce soil erosion is to?
What is plant rows of trees or grasses in lines by farm fields
200
When a glacier moves through a valley, how does it change it?
What is, widening it
300
This includes the crust and the upper layer of the mantle
What is the lithosphere.
300
If two continental plates converged, forming mountains what would happen over time?
What is the mountains would increase in height
300
The independent variable in the soil lab.
What is the type of soil with different particle sizes
300
Which of the following is not an example of erosion a. the wind in a desert blows sand against rock b. a glacier picks up boulders as it moves c. A flood washes over a riverbank, and the water carries small soil particles downstream d. An icy winter causes the road to crack
What is d. an icy winter causes the road to crack.
300
The most important condition needed for the accumulation of glacial ice
What is winter snowfall should be greater than summer melting and evaporation. (More snow than than summer melting)
400
This layer of the earth is thought to be made up of very dense material and solid.
What is the inner core.
400
When two plates are moving towards each other, and one is sliding underneath the other into an ocean trench causing volcanoes to occur.
What is subduction
400
Earthquakes occur near the San Andreas Fault because?
What is, portions of the plates get stuck and then suddenly loosen and move (faulting)
400
Which of the following is NOT considered an example of physical weathering? a. abrasion b. oxidation c. frost action d. plant growth
What is b. oxidation
400
How do glaciers erode the land?
By picking up soil and rocks and depositing them in new locations
500
This section of the Earth is molten, and can be compared to the consistency of taffy.
What is the mantle.
500
This type of plate boundary would be most likely to cause a mountain with volcanic activity
What is convergent with subduction
500
Within the next 100 million years, the Great Rift Valley in Africa will most likely become what
A wider and deeper valley
500
What causes most chemical weathering?
What is acids
500
What would cause a statue moved from Egypt to the US to crumble?
-change in environment/climate -Abrasion (wind) -Frost action (freezing/thawing)
