TECTONIC PLATES!
Karten in diesem Stapel (18)
- 1What are the three types of plate margins?Destructive, Constuctive and Conservative
- 2Destructive Plate Margins-When two plates are moving towards eachother.
-Where an oceanic plate meets a continental plate, the denser oceanic plate is forced down into the mantle. This often creates volcanoes and ocean trenches.
-Where two continental plates meet, the plates smash together but no crust is destroyed. - 3Constructive Margins-When two plates are moving away from each other.
-Magma (molten rock) rises from the mantle to fill the gap and cools. Creating a new crust. - 4Conservative Margins-When two plates are moving sideways past eachother, or are moving the same direction but in different speeds. Crust isn't created or destroyed
- 5—Destructive Plate Margin
- 6—Conservative Plate Margin
- 7—Consructive Plate Margin
- 8—Inner Core(Yellow) Outer Core(Orange) Mantle(Red) Crust(The Outside)
- 9What is the Earth's surface serperated into?Tectonic Plates
- 10The centre of the earthIt is called the core and it is a solid ball of iron and nickel
- 11The Mantleit is around the core and it's semi- molten rock meaning that it moves very slowly
- 12The crustis the outer layer of the earth and it is very thin (about 20km)
- 13Whats floats on the mantle?Lots of slabs called tectonic plates which the crust is divided into
- 14What are the two types of plates?Oceanic and continental
- 15Continental crustthicker and less dense
- 16Oceanic Crustthinner and more dense
- 17How are the plates moving?because the rock in the mantle underneath them are moving
- 18What are the places called where plates meet?Plate boundaries or plate margins
