Earth Science
The process of wind water and ice putting sown sediments they carry.
What is deposition?
The driving force behind most erosion.
What is gravity?
Small particles of rocks that form when rock breaks down.
What are sediments?
A break in the rock that makes up Earth's crust.
What is a fault?
The scientist that first proposed the idea of seafloor spreading.
Who was Harry Hess?
About __________ percent of Earth's surface is coverd in water.
What is 75%?
The breaking down of rock at or near Earth's surface
What is weathering?
If a sedimentary rock in a dry place has a fish fossil in its deep layers it means this was covering this area once.
What is an ocean?
This is the process that moves weathered materials.
What is erosion?
The cause of canyon formation.
What is river erosion?
Earth's layers of earth are ______ (in order)
What is crust, mantle, outer core, & inner core?
These processes break down rock by weathering.
What is wind, water, & gravity?
A historical sequence of life indicated by fossils found in layers of the earth's crust.
What is the fossil record?
Divergent plates are plates that pull apart from each other and this can cause these two events.
What are earthquakes and mid ocean ridges?
The theory that explains volcanoes, earthquakes, seafloor spreading, and other concepts.
What is the theory of Plate Tectonics?
When weathered rock is picked up and moved.
What is erosion?
A technique using half life to determine the age of rocks and fossils.
What is radioactive dating?
Relationship between altitude and temperature in the mesosphere.
What is an inverse relationship?
The rapid downhill movement of soil and rock caused by gravity.
What is a landslide?
A type of rock found deep underground where heat and pressure cause existing rock to be changed into this kind of rock.
What is metamorphic rock?
A fossil that is used to determine the age of a rock layer.
What is an index fossil?
When the wind/water/glacier drops the material they are eroding.
What is deposition?
The three categories of rocks
What are sedimentary, igneous, and metamorphic?
The average salinity of the ocean.
What is 3.5%?
When all of the plates and continents were together.
What was Pangea?
