45
83
52
97
What percentage of earth's water is freshwater?
97%
2%
1%

Which is the result of faulting?
The slow folding up of mountains as tectonic plates collide
A sudden earthquake as bent tectonic plates release tension
A cascade of rock and ash the spews along tectonic plate boundaries.
the destruction of undersea mountains as ocean plates slide under continental plates
Why would a geographer think understanding our solar system is important?
to track asteroids and comets so they don't collide with Earth
to map the position and orbits of our system's planets around the sun
to understand how Earth fits into this system, much as how different areas of Earth fit together
to determine which planets may have supported life in the past or be able to sustain life now
Scientists think that Pangaea separated due to
climate change
continental drift
weathering
glaciers
What does the expression "this year's rain is last year's snow" refer to
Rain in the spring can sometimes freeze due to unseasonable temperatures
snow consists of water in the frozen state and this water becomes rain when subjected to higher temperatures
the amount of water does not change and is cycled in an unending process despite its changing physical state.
the amount of rain and snow changes due to the changing amount of water that cycles through Earth's atmosphere
Most of Earth's freshwater is in
polar ice caps
oceans
rivers, lakes, and streams
vapor in the atmosphere
A part of the coastal plain that extends out underneath the ocean:
continental shelf
plate
erosion
desalination
Oceanic plates slide under continental plates and scrap off seamounts, leaving debris that causes continents TO GROW OUTWARD
accretion
water cycle
plate tectonics
desalination
The main reason for the creation of desalination plants is
to provide freshwater to support human activities
to promote jobs in high-tech industries and decrease agriculture careers
to expand trade exports of excess salt and brine processing
to provide economic stability to undeveloped countries
How can desalination plants negatively affect the environment?
Desalination emits salt into the atmosphere
Desalination plants will eventually cause the lowering of sea levels
Desalination plants produce water that can destroy arable land
Desalination plants burn fossil fuels that contribute to pollution
Most of Earth's freshwater is in
polar caps
oceans
rivers, lakes and streams
vapor in the atmosphere
Oceanic plates dive under continental plates and melt, sometimes causing magma to rise and form VOLCANIC MOUNTAINS ON LAND:
subduction
water cycle
desalination
continental shelf
