How do the earth's plates move

WebMajor and minor tectonic plates The Earth is roughly spherical, so these plates are fractured into curved sections which are in constant motion relative to each other and meet in various ways along their edges – these are the ‘plate boundaries’, where most volcanoes and earthquakes occur. WebThere are three different ways the plates move: the plates can move past each other, they can move apart from each other or they can move towards each other. Scientists have special names for the way the plates move Transform boundaries are where the plates meet and try to move past each other.

Lava flows at the surface cool rapidly to become basalt, but deeper in the crust, magma cools more slowly to form gabbro. So the entire ridge system is made up of igneous rock that is either extrusive or intrusive. WebOct 30, 2024 · The earth is affected by gravitational forces from the sun and the moon.

Plates move because of gravity, which is the main driving force behind plate tectonics. Another reason why plates move is due to convection.
