Whole body fossils are the entire remains of prehistoric organisms including soft tissue, such as insects embalmed in tree sap that hardens to create amber

what is a body fossil

200
A term to describe layered rock made of sediments.
What is sedimentary rock?
200

two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth's mantle to the surface, solidifying to create new oceanic crust. The Mid-Atlantic Ridge is an example

what is a diverging boundary

200
The thinnest layer of the earth.
What is the crust?
200
An example of this is when plants force their roots into spaces and crack rocks and soil in order to grow.
What is biological weathering?
300

is an imprint left by the shell of a hard skeleton on surrounding rock, An mold is left on the surface of rock that formed when sand or mud filled the inside of the shell and harden into rock

what is a mold or cast fossil

When you add pressure to Igneous rock this form of rock is created.
What is Metamorphic Rock?
300
What happens when an oceanic crust converges with continental crust.
What is a subduction zone?
300
A downward slow moving mass of ice and snow that carves out valleys. 
What is a glacier?
300
Shiny rocks have this quality...
What is it's lustre?
400

Provides us with indirect evidence of life in the past, such as the footprints, tracks, and burrows

What is a trace fossil?
400
This type of rock is formed from lava.
What is igneous rock?
400

 tectonic plates slide horizontally past each other.

what is a transform boundary 

400
Forces such as wind and rain that break rocks down TRANSPORTS them to other locations.
What is erosion?
400

are formed by the movement of large crustal blocks along faults formed when tensional forces pull apart the crust. Tension is often the result of uplifting part of the crust

what is fault block mountains

500

A large area in the Rocky Mountains with the best preserved soft-bodied fossils from the Cambrian explosion

The Burgress Shale

500
When a mineral splits easily into two smooth surfaces.
What is cleavage?
500
Layers of sediment that have formed over millions of years
What is strata?
500
Detects the waves in the earth caused by earthquakes.
What is a seismograph?

are created where two or more of Earth's tectonic plates are pushed together. At these colliding, compressing boundaries, rocks and debris are warped and folded into rocky outcrops, hills, mountains, and entire mountain ranges.
