What do continental masses form over?
Continental Masses form over Land.
What happens to mantle rock descending oceanic crust scrapes past continental crust?
As the oceanic crust descends beneath the continental crust, the mantle rock is subjected to high pressure and temperature. This causes the mantle rock to partially melt, producing magma that can rise to the surface and form volcanoes. The interaction of the descending oceanic crust with the continental crust can also lead to earthquake activity.
What is likely to form where oceanic crust is subducted under continental crust?
Where oceanic crust is subducted under continental crust, a trench, volcanic arc, and earthquakes are likely to form. The subduction of the dense oceanic plate causes it to sink beneath the less dense continental plate, leading to the creation of these geological features due to the intense heat and pressure generated in the process.
What is the difference between a convergent boundary between an oceanic plate and a continental plate and a convergent boundary between two continental plates?
A convergent boundary between two continental plates causes both plates to crumple to form fold mountains e.g. the HimalayasA convergent boundary between a continental and an oceanic causes one to rise above the other. Granite is less dense than basalt, so the continental plate rises above the oceanic plate. This also forms mountains, like the Andes.

What type of rocks are the starting points for continental shields
What type of rocks are the starting points for continental shields?
The starting points for continental shields are usually igneous rocks, such as granite, gneiss, and basalt. These rocks are formed from the cooling and solidification of magma deep within the Earth's crust. Over time, they can be uplifted and exposed at the surface, creating the foundation for continental shields.
Are the Continental shields and stable platforms are part of the interior region known as a craton?
Yes, Continental shields and stable platforms are both part of a craton, which is the ancient, stable interior region of a continent. Shields are the exposed areas of a craton, while stable platforms are the surrounding flat regions. Together, they form the stable interior core of a continent.
What causes an ocean trench form?
subduction of an oceanic plate under a continental plate.
The continental shelf continental slope and continental rise combine to form what?
The continental shelf, continental slope, and continental rise combine to form the continental margin.
The continental shelf, continental slope, and continental rise to form the?
continental margin
When a continental crust collides with a continental crust what is formed?
When continental crust collides with continental crust, it can form large mountain ranges through a process called continental collision. This collision causes the crust to fold and thrust upwards, leading to the formation of extensive mountain systems like the Himalayas.
Why did knights have coloured designs on their shields?
knights had coloreddesigns on their Shields as a form of identification. which means so you know who they are and which army they are from!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

What do the continental shelf continental slope and continental rise combine to form?
The continental shelf, continental slope, and continental rise combine to form the continental margin. The continental margin is the transition zone between the continent and the deep ocean basin.
What continental shelf continental slope and continental rise combine to form the?
The continental shelf, continental slope, and continental rise together form the continental margin. The continental margin is the submerged edge of a continent that consists of these three distinct but connected features.
