Geologist who became a navy sub commander in WW2. While commander he discovered mid-ocean ridges on the ocean floor. Later, took core samples of mid ocean ridges and discovered seafloor spreading
What is harry hess

One plate moves under another causing magma to be produced and makes volcanoes
What is Subduction
300
Gluing Sediments Together
What is Cementation
400
a conclusion that doesn't have 100% proof but is accepted to be true
What is theory

Dissolved Minerals Harden After Water Evaporates
What is Chemical
500
liquid,metals in the earth
What is outer core

Oceanic Crust is found under the Earth's oceans and is more dense due to compression from water. Continental Crust is crust found on land and is less dense due to less pressure.
What is plate tectonics
500
A solid and lessens earthquake damage. Poorly consolidated ground increases earthquake damage.
What is Bedrock vs. Poorly Consolidated Ground

Located in Washington State, Major Eruption in 1980 when North Side of the Volcano blew off causing a massive landslide and covered the region with pyroclastic flow. The flow knocked down trees and destroyed life in the region. 57 people killed in the blast.
