What is formed when magma begins to firm a dome shape which will push the crust outward in a hill formation?
When magma begins to rise and form a dome shape, it creates a geological structure known as a volcanic dome or lava dome. As the magma collects beneath the Earth's crust, it exerts pressure, causing the overlying crust to bulge outward and form a hill-like formation. This process can lead to the accumulation of viscous lava, resulting in a steep, dome-shaped feature. Over time, these domes can become significant landmarks and may also pose volcanic hazards if they erupt.
What is formed when magma begins to form a dome shape which will push the rust outward in a hill formation?
When magma pushes upward in a dome shape, it creates a geological feature known as a volcanic dome or lava dome. This occurs when viscous lava accumulates at a vent, causing the surrounding rock to bulge outward. As the dome forms, it can lead to the uplift of the crust, resulting in a hill-like structure. Volcanic domes are often associated with explosive eruptions as the pressure builds within the magma chamber.
How is new crust continually being formed?
New crust is continually being formed at mid-ocean ridges through the process of seafloor spreading. Magma rises from the mantle and solidifies at the ridges, creating new crust as tectonic plates move apart. The crust then slowly spreads outward as more magma comes up, constantly renewing the Earth's surface.
When the crust of the earth is thin and can be ruptured a what can be formed?
When the crust of the Earth is thin and ruptured, it can lead to the formation of rift valleys, such as the East African Rift. This process can also result in the formation of new ocean basins through seafloor spreading.
What modern process is thought to be similar to the way crust formed before plate tectonics began?
The formation of the Hawaiian Islands

When is crust neither formed or destroyed?
Crust is neither formed nor destroyed when the rate of crust formation at mid-ocean ridges equals the rate of crust destruction at subduction zones. This balance is known as isostasy and helps maintain the overall thickness of the Earth's crust.
What does the formation of a crater follow?
There are craters formed by asteroids crashing into Earth. There are craters formed by volcanic explosions. There are craters formed by collapses in the Earth's crust.

Which boundry does a rift valley forrm at?
divergant boundries. new rock is formed and pushes the older seafloor outward towards the continental crust.

Where are oceanic crust and lithosphere formed?
Oceanic crust and lithosphere are formed at mid-ocean ridges through the process of seafloor spreading. Magma rises from the mantle and solidifies to create new oceanic crust at these divergent plate boundaries. As the new crust forms, it pushes the older crust away from the ridge axis, creating a continuous process of crust formation and movement.
The oceanic crust begins at the continental shelf or rise?
The oceanic crust begins at the continental rise
What is the outcome of two plates moving apart?
When two plates move apart, a divergent boundary is formed. This movement creates a gap which allows magma from beneath the Earth's crust to rise, leading to the formation of new crust. Over time, this process results in the creation of new oceanic crust and the widening of the ocean basin.
What features are commonly formed at the plate boundaries where continental crust converges with oceanic crust?
Subduction zones are commonly formed at these plate boundaries, where the denser oceanic crust is forced beneath the less dense continental crust. This process can create deep oceanic trenches, volcanic arcs, and earthquakes. Over time, it can also result in the formation of mountain ranges on the continental crust.
