Where are rift boundaries formed at and what happens at them?
A rift boundary is a divergent boundary, where two plates of the earth's crust are moving away from each other. Divergent boundaries occur at mid-oceanic ridges on the sea floor, but usually the term rift is used to describe divergent boundaries on the land. The best known one is in eastern Africa.
A divergent boundary is different than a convergent boundary in that?
Divergent and convergent boundaries are two of three primary Tectonic plate boundaries, the third being Transform boundaries. These plates change the surface of the Earth. As divergent boundaries pull apart, layers of new crust build up on both sides of the breaking land mass, causing a rift/divide. The surrounding body of water, if one is present, eventually fills this space. Convergent boundaries are the result of Earth's plates clashing and one going beneath the other. Instead of crust building it is eliminated and returned to the Earth to be recycled for use again. A term applied to this occurrence is Subduction Zone; often seen with convergent boundaries are the formation of volcanos and mountains.
What geologic feature is associated with rift eruptions?
Earth quakes and also divergent plate
How do valcanoes form at divergent plate boundaries?
Beneath the Earth's crust is a lot of magma. Thus as the plates pull apart, it leaves a gap through which the magma can travel and erupt as lava. For example at the Mid Atlantic Ridge, there are divergent plate boundaries. The 'gap' between the divorcing plates allows magma to boil through, building up the ridge in the process.
What is the earth's crust separated into?
The Earth's crust is separated into different plates. These plate move causing plate tectonics, which is the movement of Earth's crust. Also, the plates have boundaries at the end of each plate. There are three types of plate boundaries... 1. Divergent- where two plates are moving away from each other forming a gap in the crust in which magma rises and hardens forming new crust. 2. Convergent- Where two plates are coming into one another and one is forced down into the mantle. 3. Transform- Where no crust is destroyed/created because the two plates just slide past each other.
What are Cracks in the earths crust called?
Divergent boundaries, convergent boundaries, and transform boundaries are all cracks in the Earth's crust. They are located where the Earth's plates border one another.
What plate boundaries are where the crust forms?
new crust forms at divergint bounderies where plates move apart magma oozes up and cools down and creates new crust and the old crust moves away and sucks in the earth
How is the Earth's crust created and destroyed?
It is created at mid-oceanic ridges (divergent boundaries) and it is destroyed at subduction zones (convergent boundary between oceanic crust and continental crust).
Where does new crust forms..?
New crust is formed at divergent boundaries. While an equal volume of new crust is forming the Earth still remains the same size.
Is the pressure on the earth's crust equalized?
No, pressure on the crust of the earth is not equalized. We have plate tectonics and the shifts associated with tensions between the plates acting to cause uplift at convergent boundaries and rifting as divergent boundaries as just two examples. A link is provided below.
What is deep oceans trenches?
a deep-ocean trench is a portion of the earth crust

What are divert boundaries?
divergent boundaries are under the ground earth quakes
Where do earth's plates move around?
at divergent boundaries

What are the different types of boundaries found along the edges of the earth plates?
convergent boundaries, divergent boundaries, transform boundaries and plate boundaries
