The area on the surface directly above where an earthquake has occurred
Why are tar, amber and ice fossils valuable to paleontologists?
The soft tissues (hair, skin organs) are preserved and can be studied

What type of scientists study fossils?
Paleontologist
What is the pacific ring of fire
The Ring of Fire is a tectonic belt of volcanoes and earthquakes. It circles the pacific ocean
This type of igneous rock is created when the magma cools within the earth's crust.
Intrusive igneous rock (ex. granite)
How do paleontologists use index fossils
To determine the age of the rock layers they are found in
This type of rock is created by compaction and cementation of individual sediments.
sedimentary rock
Fossils can be created in many different ways. What is the name given to fossils created when minerals transported by water fill open spaces in organisms and harden?
Permineralization
Alfred Wegner is one of the most famous geologists of all time. What was his famous theory that was proven after his death?
When plate tectonics meet, it is called a boundary. There are three types of boundaries. Name and explain 2 types
Divergent - Moving apart
Convergent - Coming together
Transform - Sliding against each other
what two processes are required for a rock to become a metamorphic rock
Heat and pressure
Fossils are only found in this type of rock
sedimentary
Describe the weathering process
The breakdown of rocks into smaller rocks we call sediment. Water, wind and ice are common causes.
