Which statement best suits the definition of a coast.

• A coast is any environment where land meets water.

• Coasts only include the shoreline up to the back shore.

• A coast refers to any of the offshore marine environments beyond the terrestrial.

• Coasts are the intersection of marine and terrestrial environments.

This diagram shows the zones contained within a coastal environment.

From left (ocean) to right (terrestrial), identify the zones.

• Dunes, backshore, foreshore, nearshore, offshore.

• Offshore, nearshore, foreshore, backshore, dunes.

• Foreshore, offshore, shoreline, rear shore, beach scrub.

• Offshore, shallows, foreshore, dunes, back shore.

The region of coast that is periodically exposed to either open air and submerged is known as the i_ zone.

Which summary best suits the cause of tides?

• Tides are caused by a combination of the moon's gravity and Earth's momentum.

• Tides are caused by the influence of gravity by the moon and sun.

• Tides are caused by the momentum of Earth's rotation.

• Tides are caused by the uneven pull of gravity across the Earth.

Which statement about coastal substrates is incorrect?

• Coastal sediments are the result of sand moved from the seafloor to the shore.

• Coastal sediments are determined by the composition of terrestrial substrates.

• Younger land masses generally have beaches with narrower beaches and larger grained sediments.

• Older land masses generally have beaches with finer sediments.

A majority of rocky outcrops in the intertidal zone at Point Peron shared a common feature. What was it?

• Sharp jagged edges

• Rounded edges

• Mix of various shapes and edges

• They were all granite

Due to erosion, what areas have developed into habitats for marine life?

How has the prevailing wind affected erosion in this location?

• Wind influences the movement of water. Westerly winds have driven water to erode the east side more.

• Wind directly erodes soils. Westerly winds have exposed the rocky substrate.

• Wind directly erodes soils. Easterly winds have exposed the rocky substrate.

• Wind influences the movement of water. Westerly winds have driven water to erode the west side more.
