Name the parts of the ocean..

• Continental shelf, continental slope, continental rise, abyssal plain, seamounts, ocean trenches

• Continental shelf, continental slope, seamounts

• Ocean trenches, continental rise, continental slope

What is the continental shelf?

• flat bottom of the ocean

• A very deep canyon on the ocean floor

• part of the ocean floor, made of think sand, mud and rocks, that starts at the shore and gradually slopes underwater

• undersea mountains formed by erupting volcanoes

What is the abyssal plain?

• flat bottom of the ocean that is covered with sand and the remains of dead plants and animals

• A very deep canyon on the ocean floor

• part of the ocean floor, made of think sand, mud and rocks, that starts at the shore and gradually slopes underwater

• undersea mountains formed by erupting volcanoes

What are seamounts?

What are three basic motions of ocean water?

• currents

• tides

• seamounts

• waves

What are currents?

• huge waves

• ocean waters that move in huge circular motion

What causes currents?

• wind patterns

• the moon

• temperature

• salinity

What is salinity?

• the amount of marine life in the ocean water

• how high the water rises

• how fast waves are formed

• the amount of salt in the ocean water
