1.this is due to longshore currents

2.this is due to the circular orbital motion of waves

3. this is due to the Coriolis effect

-the freezing and melting of continental glaciers can cause eustatic changes in sea-level.

-eustatic sea-level changes are a worldwide phenomenon resulting from changes in the holding capacity of the ocean basins or the amount of water in them.

-thermal expansion or contraction of water due to global warming or cooling can cause tectonic changes in sea-level

-increasing the sediment load deposited at continental margins contributes to tectonic uplift

-tectonic uplift is occuring along the west coast of the US as a result of the collision of the North American Plate with the Pacific, Juan de Fuca, & Gorda Plates

-tectonic changes in sea level result from uplift or subsidence of a continent along a shoreline segment as a result of processes related to global plate tectonics

-for relative rises in sea level, marine terraces and stranded beach deposits are left as evidence

-along the east coast, tectonic events if a more passive nature are causing the shoreline to subside due to thermal contraction as the continent moves farther from the Mid-Atlantic ridge

3 You and a friend set up an umbrella and chairs at a beach. Your friend then goes into the surf zone to play Frisbee with another person. Several minutes later, your friend looks back toward the beach and is surprised to see that she is no longer near where the umbrella and chairs were set up. Although she is still in the surf zone, she is 30 or 40 meters away from where she started. How would you explain to your friend why she moved along the shore? Compare the causes and effects of tectonic versus eustatic changes in sea level. Select the answers below which are correct. There may be more than one correct
