earth science final-

Question 1

Water is responsible for

Answer 1

the weathering of the Earth’s surface, deposition on the Earth’s surface, and eroding the Earth’s surface

Question 2

Constructive forces

Answer 2

Build up Earth’s surface and land forms. includes deposition (accumulation of sediment - sand dunes and islands), volcanic eruptions (molten and islands), crustal deformation (mountain building and rift valleys)

Question 3

Deconstructive forces

Answer 3

Weathering of rocks (by wind, water, and temperature), Erosion (removal and transportation of materials). Forms canyons, river valleys, and coastal erosion.

Question 4

Mountain ranges blocking rainfall and creating rain shadow is an example of

Answer 4

Geosphere and Atmosphere

Question 5

Ocean supporting many ecosystems including coral reefs and tide pools is

Answer 5

hydrosphere and biosphere

Question 6

Caves are example of

Answer 6

Geosphere carved out by hydrosphere

Question 7

Identify processes of carbon cycle and their impacts

Answer 7

Respiration (fast… performed by all living things); includes decomposition
Photosynthesis (fast… performed by plants); acts as a carbon sink, which helps regulate the amount of carbon in our atmosphere. Also stores energy to be consumed by herbivores and predators.
Exchange (dissolves into water, ocean releases it back); CO2 also combines with calcium ions to form calcium carbonate.
Sedimentation (slow…calcium carbonate solidifies); once precipitates out of water, forms limestone and dolomite rock through sedimentation and burial.
Burial; slow… small fraction of organic carbon in biomass incorporated into ocean sediments that become fossilized
Extraction; removal of fossil fuels like coal, oil, and natural gas (does not alter carbon cycle)
Combustion (fast) does release carbon into atmosphere
