A device that bounces sound waves off underwater objects and then records the echoes of these sound waves.

"New" crust is created at this site
What is mid ocean ridges
200
The process by which ocean floor sinks beneath a deep-ocean trench and back into the mantle
What is subduction
200
Ms. David was 17 when she graduated high school in 1983. If her birthday is on December 25th, how is she today?
What is 48
300
3 kinds of evidence that Alfred Wegener examined to support his idea of continental drift
What is land features, fossils and climate change
300
The 3 main plate boundaries
What is divergent, convergent and transform boundaries
300
Crust is "destroyed" at this site
What is deep-ocean trenches
300
The boundary where 2 plates are slipping past each other - earthquakes often occur at these boundaries
What is a transform boundary
300
List last yearʻs team 7B advisory teachers
What is Mr. Nakata, Ms. David, Mrs. Muralidharan, Mrs. Tom, Mr. Koga, Mr. Matsuura, Mr. Arakaki
400
The reason why Alfred Wegenerʻs theory of Continental Drift was rejected
What is Alfred Wegener was unable to explain how continents were "pushed" or "pulled" around. He suggested that continents were plowing across the continental floor.
400
Features that form at convergent boundaries (2)
What is Islands arcs, trenches and mountain ranges
400
Types of evidence supporting sea floor spreading
What is eruptions of molten material, magnetic stripes in the rock, ages of the rocks themselves
400
The Marianas Trench and the Himalayan Mountains are features at this type of plate boundary
What is a convergent boundary
400
Match each of the Hawaiian islands with their associated color. Islands: Hawaii, Maui, Molokai, Lanai, Oahu, Kauai, Niihau, Kahoolawe Color: gray, white, pink, orange, yellow, green, red, purple
What is Hawaii-red, Maui-pink, Molokai-green, Lanai-orange, Oahu-yellow, Kauai-purple, Niihau-white, Kahoolawe-gray
500
The "forces" that are actually responsible for moving continents.
What is convection currents in Earthʻs mantle
500
Features that form at divergent boundaries (2)
What are rift valleys and mid-ocean ridges
500
The process of sea-floor spreading. (Must include the following terms - mid ocean ridge, conveyor belt, continents)
What is when the sea floor spreads apart along both sides of a mid-ocean ridge as new crust is added. As a result, the ocean floors move like conveyor belts, carrying the continents along with them.
500
The Mid-Atlantic ridge and the East African Rift are features that at this type of plate boundary
What is divergent boundary
500
Mid-Ocean ridges extend in to all of Earthʻs oceans. These mountains are miles high and are the tallest in the world. Mid-Ocean ridges normally lie hidden under hundreds of meters of water. Provide an example of where a ridge rises above the surface of the water (name the place).
What is Iceland.
