What else can I help you with?
Why are there are almost no extrusive ultra basic rocks in earths crust?
There are almost no extrusive rocks on the earths surface because they are all under the earths surface. They are mainly lower than the earths surface.
What are moving pieces under the earths surface that form the earths crust?
Tectonic plates are the moving pieces under the Earth's surface that form the Earth's crust. These plates float on the semi-fluid asthenosphere and interact with each other through processes like subduction, spreading, and collision, which contribute to the shaping of Earth's surface features.
The surface of the earth moves violently in an what?
The surface of the earth moves violently in an earthquake. This occurs when there is a sudden release of energy in the earths crust. Anything from a volcano to a tectonic plate shift can cause an earthquake.
How does an active volcano effect earths surface?
an active volcano affects the surface because of where the place is located
What is the earths lithosphere broken up into?
Tectonic Plates
What forces below earth surface shape landforms?
The tectonic plates below earths surface shape earths landforms
Why you have an earthquake?
the tectonic plates are shifting under the earths surface.
What moves the ocean floor?
the tectonic plates under the earths surface
What are most earthquakes cause by?
moving tectonic plates on earths surface
Do tectonic plates cover the earths entire surface?
94% of the earth. yes
What processes do scientist infer to have shaped earths surface in the past?
The shifting of Tectonic Plates.
How do covergent boundary plates affect earths surface?
The tectonic plates combined together
What causes volcanoes to erupt under earths surface?
mostly earthquakes or plate tectonic movement.
Where do earthquakes usually occurr?
Earthquakes ussually occur near the tectonic plates which cover the earths surface.
If the lithosphere moved less how would the surface of the earths be affected?
the pushed and pull of tectonic forces would decrease.
Why are there are almost no extrusive ultra basic rocks in earths crust?
There are almost no extrusive rocks on the earths surface because they are all under the earths surface. They are mainly lower than the earths surface.
What can tectonic plates form when they divide?
When tectonic plates divide they create divergent boundaries, which can cause the earths surface to divide and split up, almost like when you rip a piece of paper
