What happens when a earthquake is underwater
A tsunami wave starts
Plates that slip/slide past each other are
Its Transforming Plates
How are volcanoes formed
Magma is formed down in the earths crust and is pushed downwards in a very hot area where it melts and then the magma is forced up a vent. Its called magma underground and lava on the survace
What is a Surface wave
Slowest earthquake but strongest
What boundries does an earthquake use
Converging, Diverging, and Transform
What boundries does a volcano use
It uses Converging
How can you tell the age of a mountain?
Seeing if it has jagged for rounded edges
younger- jagged
older- rounded
What is a Secondary wave
A earthquake that is slower then primary but is much stronger can only travel from solids
Plates that are pushing against each other is a
Its a Converging Plate
Plates that are pushing away from each other are
Its a Diverging plates
What is a slip/strike/transform fault
Caused by slipping and is moving beside each other till it gets stuck and then its forced to break apart causes biggest earthquake
What is a Primary wave
Fastest Earth quake but is really weak can travel through liquids, solids, and gasses
What is Theory of Tectonics
It is a explanation of earthquakes, volcanoes, and mountains
Who was Wengener
The person who created the theory for Continental Drift
What is a reverse fault
Its a reverse of a normal fault caused by compression and it has a deeper earthquakes
What is a normal fault
Its caused by stretching apart and it has shallow earth quakes
What is a Subduction Zone
What is Fault Block Mountains
Are formed by thrust faulting
What is Folded Mountains
Rock bends and folds when heated and preasure added
What is the proof that Continental Drift exists
(give five examples)
1. Continents fit like puzzle pieces
2. fossils of our planet were found in different continents
3.Some mountain ranges were found on opposite sides of the ocean
4.fossils from the bottom of the ocean were found in mountains
5. Glacial deposits are evidence of glacier movement and directions of travea
