How are the plate tectonics change the world
that we living?
Plate tectonics are form by crust
of the land. Are two types of crust oceanic vs. continental. The difference is
that one is under the ocean and the other one is made by rock underneath.
Convection currents are the force that helps move plates ways of each others.
During this process realized 3 types of boundary.
A tectonic boundary where two plates are moving away from each other and new crust is forming from magma that rises to the Earth's surface between the two plates. creating mid ocean and rift valley.
Convergent boundary
A tectonic boundary where two plates are move and push up against each other make a hole call trench. creating a mountain or a volcano.
Transform boundary
A tectonic boundary where two plates are move slide against each other creating Earth quakes.
A tectonic boundary where two plates are move slide against each other creating Earth quakes.
How the
Volcanoes are Form
When are convergent plate
pushing the continental crust makes a mountain or a volcanoes are formed by
magma is a hot fluid or a liquid rock inside of volcano. When the magma and
crust meets together makes lava. What are different stages of volcanoes Active:
Is a volcano which has recently erupted. Dormant eructed: is volcano which has
not erupted in long time Extinct: are volcanoes which have not eructed of
thousands years ago. Different types of volcanoes Cinder cones: circular or
oval cones made up f small fragment of lava. Composite volcanoes: composed of
many layers of volcanoes rock, hot spot or busy lava. Shield volcanoes: shape
of the volcanoes made by basaltic lava flows. Lava volcanoes: lava is formed by
steam. What the different is between lave and magma Lava is liquid rock that
flows out of the volcano. Magma is liquid rock inside a volcano.
