Rock Cycle
The three main rocks of the Rock Cycle...
What is metamorphic, igneous, & sedimentary?
The definition of a fossil is
Evidence of past life that have been preserved in rocks.
What is the definition of weathering?
When rocks are broken down into smaller pieces.
What is absolute dating?
The exact age of something.
Alfred Wegener studied what?
Continental Drift
The rock that forms mainly from heat and pressure
What is metamorphic rock?
Woolly Mammoths or Sand?
Woolly Mammoths
What is the definition of erosion?
When small pieces of rock (sediment) are moved around by wind and/or water.
What is relative dating?
The age of something based on its placement
Harry Hess studied what?
What is sea floor spreading?
Igneous rock
The name of the geologist that found tropical plant fossils on islands in the arctic ocean
Who is Alfred Wegener?
What is an agent of weathering?
Wind, Snow, Rain, Ice, Hail
What are plate tectonics?
The movement of Earth’s plates that can cause rock layers to move
What did J. Tuzo Wilson study?
What is plate tectonics?
The rock that forms of erosion, compaction, and cementation
What is sedimentary rock?
What caused dinosaurs to go extinct?
A big meteor hit Earth, and scientists know this because they have found a rock layer they named the K-T boundary that show dinosaurs living before that layer but none after.
What is the definition of deposition?
When sediment stops moving and collects in a new area.
What is sedimentary rock?
Rock that forms when sediment from erosion is compressed together
What is intrusion?
When molten rock from inside Earth moves through cracks in the rock layers. This molten rock will sometimes reach and break through the surface.
The two types of igneous rock that form inside and outside of a volcano?
Intrusive and Extrusive
What is a Palaeontologists?
Gravity is an agent of erosion....True or False?
True
What is the geological time scale?
Arrangement of events used as a measure of the relative or absolute age of any part of geologic time
What is extrusive igneous rock?
Rock that forms outside of a volcano.
