What is a wave?

What is a wave?

• A static form in the ocean

• A rhythmic movement that carries energy through matter and space

• A random movement of air

• A type of ocean animal

What causes water to begin to pile up, forming a wave?

• The water temperature

• The wind blowing across a body of water

• The gravitational pull of the moon

• The rotation of the Earth

On what does the height of a wave depend?

• The depth of the water

• The speed of the wind

• The distance over which the wind blows

• The length of time the wind blows

Which factor is NOT mentioned as affecting the height of a wave?

• The speed of the wind

• The distance over which the wind blows

• The length of time the wind blows

• The salinity of the water

What happens to waves once they are set in motion?

• They immediately stop

• They continue moving for long distances even if the wind stops blowing

• They change direction and move towards the wind

• They only move a short distance before disappearing

• In a nearby lake

• Halfway around the world

• In the deep ocean floor

How do surface currents move water?

• Vertically - perpendicular to Earth's surface

• In a straight line from pole to pole

• Horizontally - parallel to Earth's surface

• In a random pattern

What powers surface currents?

• The moon's gravitational pull

• Ocean salinity levels

• Wind

• The Earth's rotation

What patterns does the wind force the ocean to move in?

• Linear patterns

• Random patterns

• Huge, circular patterns

• Small, elliptical patterns
