Unit 2 Exam Part 1

Define what is meant by the term "littoral zone" also known as the "intertidal zone"

• The high tide mark on the sandy shore

• The area between high and low tide where the land meets the sea

• The area of a muddy shore that meets the sea

• The area of a shore that suffers from high litter count

Compare the formation of a rocky shore with that of a sandy shore

• Rocky shores have more weathering and erosion due to high wave action whereas sandy shores have higher sedimentation

• Rocky shores have more sedimentation and erosion due to high wave action whereas sandy shores have higher weathering

• Rocky shores have more weathering and sedimentation due to high wave action whereas sandy shores have higher erosion

• Sandy shores have more weathering and erosion due to high wave action whereas rocky shores have higher sedimentation

State a defining feature that distinguishes a delta from an estuary

• Deltas are where the land meets the sea, estuaries are blocked off from the ocean

• Estuaries are triangular shaped and deltas are muddy

• Deltas are freshwater and estuaries are brackish

• Estuaries have high wave action and deltas have low wave action

Describe the type of movement that happens at a convergent boundary

• The plates slide past each other

• The plates run into each other and push up or subduct

• The plates move away from each other and make room for new crust to rise up

• This is only the place where continental crust meets oceanic crust and creates a subduction zone

Describe the type of movement that happens at a transform boundary

• The plates slide past each other

• The plates run into each other and push up or subduct

• The plates move away from each other and make room for new crust to rise up

• This is only the place where continental crust meets oceanic crust and creates a subduction zone

Describe the type of movement that happens at a divergent boundary

• The plates slide past each other

• The plates run into each other and push up or subduct

• The plates move away from each other and make room for new crust to rise up

• This is only the place where continental crust meets oceanic crust and creates a subduction zone

State where you would expect to find hydrothermal vents.

• Near volcanoes

• On a convergent boundary

• At the bottom of the ocean on a divergent boundary

• At the bottom of the ocean on a transform boundary

Not including the Coriolis effect, state two physical factors that could impact the flow of the ocean currents

• Salinity and density

• Stronger than usual winds

• The gravitational pull of the sun and moon

• The rotation of the Earth as it orbits the sun

The Benguela current flows along the Western Portion of Southern Africa from Cape Point in the south northward. Each year it brings cold, nutrient-rich water to the coastlines in this region. State the name of the process described.

• High Tide

• Coriolis Effect

• Convection Currents

• Upwelling

Name two things other than gravity that impact the tides

• The sun and moon

• Wind and air pressure

• Upwelling

• Salinity and density
