Category 1
The vibrations in the ground that result from the movement along breaks in Earth's lithosphere
Earthquake
The preserved remains or evidence of past living organisms.
Fossil
Earth's magnetic field reverses direction.
Magnetic Reversal
States that Earth's surface is divided into large plates of rigid rocks that move with respect to each other
Plate Tectonics
The mountain ranges in the middle of the oceans.
Mid-Ocean Ridge
A vent in Earth’s crust through which molten rock flows.
Volcano
The denser plate sinks below the more buoyant plate.
Subduction
Forms where two plates slide past each other.
Ocean Basin
Hypothesis which suggests that continents are in constant motion on the surface of Earth.
Continental Drift
Forms where two plates collide
Convergent Plate Boundary
Produces an eruption of more than 1000 cubic kilometers of material.
Super Volcano
Movement caused by warmer fluids rising and cooler fluids sinking.
Convection
These are two types of natural disasters that occur at plate boundaries.
Earthquakes & Volcanoes
This Johnny Cash song also refers to the volcanic activity that surrounds the pacific ocean.
The Ring of Fire
The boundary between two plates that move away from each other.
Divergent Plate Boundary
A column mantle that is hotter than the surrounding material.
Hot Spot
The bubbles coming from the ocean floor in the warm up phenomenon (one word)
Fumaroles
The solid layer of Earth’s mantle below the lithosphere that is so hot it behaves like a plastic material.
Asthenosphere
This everyday item will be checked next week to make sure we are using it.
Planner
Forms where two plates slide past each other.
Transform Plate Boundary
The principle that in undisturbed rock layers, the oldest rocks are on the bottom.
Superposition
When two tectonic plates slowly crash into each other and mountains are formed.
Uplift
The rigid outermost layer of Earth that includes the uppermost mantle and crust
Lithosphere
These are the 3 main layers of Earth
Crust, Mantle, & Core
The process by which new oceanic crust forms along a mid-ocean ridge and older oceanic crust moves away from the ridge.
Seafloor Spreading
