Fossils
Layers of the Atmosphere
100
The Earth's crust and upper mantle are broken into large sections called this.
What are plates?
100
The name of the large landmass that slowly broke apart and drifted to the continents' now current locations.
What is Pangaea?
100
The breaking down of the Earth's crust into smaller and smaller pieces.
What is weathering?
100
The remains, imprints, or traces of prehistoric organisms.
What are fossils?
100
As altitude INCREASES, air pressure does this.
What is DECREASES?
200
The type of plate boundary where plates are moving in opposite directions away from each other.
What is a divergent plate boundary?
200
A piece of evidence that helped prove Continental Drift Theory showing that the shape of the continents look like they fit together.
What is puzzle-like fit of continents?
200
The process by which the surface of the Earth is constantly being worn down and CARRIED AWAY.
What is erosion?
200
Fossilized bones, teeth, and shells are this kind of fossil.
What is permineralized remains?
200
This is the layer of the atmosphere we live in.
What is the TROPOSPHERE?
300
Type of plate boundary where plates slide past each other in opposite directions, OR in same direction at different speeds.
What is a transform plate boundary?
300
Remains of mesosaurus have been found in South America and Africa.
What is fossil clues?
300
The four main forces of erosion.
What are wind, water, gravity, and glaciers?
300
The type of rock in which most fossils are found.
What is sedimentary rock?
300
This layer of the atmosphere contains the ozone layer which protects us from the sun's harmful UV radiation.
What is the STRATOSPHERE?
400
The cycle of heating, rising, cooling, sinking in the mantle thought to be the force moving the plates.
What are convection currents?
400
Fossilized tropical fern plants have been found on the island of Spitsbergen in the Arctic, showing that Spitsbergen once was near the equator.
What is climate clues?
400
Type of mechanical weathering where water seeps into cracks in rocks, freezes, and expands.
What is FROST ACTION/ICE WEDGING?
400
Fossilized footprints, dung, nests, and other evidence of an organism's activity are this type of fossil.
What is a trace fossil?
400
Commercial jet airplanes fly in these two layers.
What are the troposphere/stratosphere?
500
Two types of features OR events that occur along plate boundaries.
What are earthquakes, volcanoes, mountain building, deep sea trenches, subduction zones, rift zones . . .
500
Matching rock layers in mountain ranges on different continents have been found (same age and type of rock)
What is rock clues?
500
Type of weathering where minerals in rocks are dissolved or changed into other substances.
What is CHEMICAL weathering?
500
This idea states that in undisturbed rock layers, the oldest fossils are found in the bottom layers, and youngest fossils are found in the top layers.
What is the Principle of Superposition?
500
This is the hottest layer of the atmosphere.
What is the THERMOsphere?
