How have crustal plates moved over time?
Molten magma from the mantle rises at the top oceanic ridge, cools and solidifies, continually forming a crustal plate. Hundreds to thousands of miles from the ridge the plate moves downward into the mantle at the contact with another plate and melts. The continuous process resembling a large "conveyor belt" moves the crustal plate a few centimeters each year.
What natural events can occur when crustal plates move over each other?
earthquakes and tsunamis
Why are mountains and earthquakes two geologic features found on earths surface that are caused by the movement of crustal plates?
They are geologic features because when the crustal plates move its makes cracks on earth the the mountains are one because everytime the crustal plates move it breaks the earths surface and the dirt and rocks start gathering together
Why are large powerful earthquakes generated at subduction zones?
Subduction zones are locations where crustal plates are being forced down into the mantle below other crustal plates. These movements are not uniform, but instead occur in discrete events. This is because friction causes the plates to lock in position until the stress exceeds the shear strength of the fault zone. This accumulation of stress causes deformations in the rock mass around the locked fault which is suddenly released when the fault slips.
What is crustal Compression?
Crustal compression is the process where tectonic forces squeeze rock layers in the Earth's crust, causing them to deform and fold. This can lead to the formation of mountain ranges or fault lines as the rocks are pushed together and uplifted. Compression can occur at convergent plate boundaries where two tectonic plates collide.

When did the first impact of crustal plates occur in the area that is now New England?
tectonic plates

What is likely to occur on the earth's surface where it lies above the edges of crustal plates?
volcanoes,earthquakes,mountains

Why do earthquakes occur in subduct?
Subduction zones are locations where crustal plates are being forced down into the mantle below other crustal plates. These movements are not uniform, but instead occur in discrete events. This is because friction causes the plates to lock in position until the stress exceeds the shear strength of the fault zone. This accumulation of stress causes deformations in the rock mass around the locked fault which is suddenly released when the fault slips.
What happens when crustal plates slide past each other?
When crustal plates slide past each other, they create faults along the plate boundaries. Friction between the plates can cause them to get stuck, leading to stress buildup. When this stress is released, it generates earthquakes.
Do trenches occur where plates are moving apart?
Trenches form where plates are moving towards each other in a convergent plate boundary, not where they are moving apart. At divergent boundaries, such as mid-ocean ridges, plates are moving apart, creating new crust.
How are divergent plates different from convergent plates?
Divergent Boundaries happen when two plates (oceanic or contental) begin to diverge, or move apart. Convergent Boundaries occur when two plates (again, oceanic or contential) begin to converge or move apart
What are 3 earth features along the crustal plate boundaries?
Three features along crustal plate boundaries are earthquakes, volcanoes, and mountain ranges. Earthquakes occur due to the movement of tectonic plates, volcanoes form at convergent boundaries where plates collide, and mountain ranges are often found at convergent boundaries where plates push against each other.
Where do most earthquakes and volcanos occure?
they are formed along the crustal movements of the earth.
In which earth layer does crustal plate movement occur because of convection cells?
Crustal plate movement due to convection cells occurs in the asthenosphere, which is a semi-fluid layer beneath the lithosphere. The heat-driven convection currents in the asthenosphere cause the overlying crustal plates to move and interact with each other.
