What was the hypothesis that happened to all the continents?
They broke up and drifted to their current locations
How did fossils support Wageners theory?
It explains why animals and species are on opposite sides of the ocean.
Three types of tectonic plate boundaries
1. Convergent Boundary
Density changes in the asthenosphere are caused by the flow of _______ energy from deep within the Earth.
What can form when compression squeezes rocks at a convergent place boundary?
Large mountains can form
What type of mountain range is formed when tension causes large blocks of crust to drop down?
Fault Block mountains
Hypothesis that states that the continents were once one large mass that broke apart
How does the chemical composition of the different layers (crust, mantle, and core) vary
They have different densities
-The core being most dense, crust being least
-Core has lots of iron making it dense
How is the magnetic field of the earth produced
By the magnetic poles when they revers our compasses are then read opposite
the process of wearing down a missing layer that exists between horizontal and folded rock layers
How are rock layers arranges in the geologic column
oldest rocks are on the bottom, youngest are on the top
How are trade winds formed bases on convection and the difference in air pressure
The earths rotation and air pressure is involved when the low pressure has high pressure pushing against it, making it form wind.
How is differences in heating of land and water as well as difference in pressure cause the breezes to form
A sea breeze is a breeze coming from the sea, which makes the water cooler, the high pressure sinks then heats the land, then rises again. The land heats faster because the sun only has to hear the top surface and the water moves, making it harder to heat.
When changes in pressure, temperature, or chemical make up alter a rock, _________ takes place
Seven Layers of the Rock Cycle
1. Weathering and erosion
4. Heat and Pressure
How is sedimentary rock formed
When compacting of existing rocks they are weathered and eroded into tiny particles, then are pressured which creates rock
What are two things that makes different minerals unique?
Composition- shape, color, etc
Place of origin
