Are sedimentary rocks formed when sediments are compacted by extreme pressure?
Clastic and organic sedimentary rocks like conglomerate, coal, some limestones, and shale, are formed under pressure from overlying sediments.
How do mafic volcanic rocks get to Earth's surface?
Pressure from overlying crust forces mantle magmas through cracks to Earth's surface. These magmas erupt out of volcanoes, cool, and solidify into rock.
What happens when rocks are under great heat and pressure?
it will turn into metamorphic rock
What happens to Earth surface when horizontal pressure is applied to rocks?
When a horizontal pressure is applied to rocks, the earth's surface will form lines that are perpendicular to the direction of the pressure. This can be compared to folds in a wrinkled rug lying on a floor.
How does metamorphic rock develop?
Heat and pressure from overlying rock layers (or heat from adjacent magma) causes the atoms of the original rock to ionize and recrystallize. Metamorphic rocks are more dense and structurally stable than the 'protolith' from which they are formed.
What keeps the rocks inside the earth in molten state?
Radioactive decay in the inner core of k40 U238 and Th232 cause the earths internal heat plus lithostatic pressure (pressure of the overlying rocks).
High pressure and high temperature cause rocks to?
High temperature and pressure can cause rocks to change their forms. This is known as metamorphic.High pressure and high temperature can cause rocks to change forms. This is known as metamorphic.
Changes in pressure which can cause rocks to crack is an example of what?
Changes in pressure which can cause rocks to crack is an example of mechanical weathering. It refers to the disintegration and decomposition of rocks.
Are sedimentary rocks formed when sediments are compacted by extreme pressure?
Clastic and organic sedimentary rocks like conglomerate, coal, some limestones, and shale, are formed under pressure from overlying sediments.
Where does all the force come from to squeeze sediments together to form sedimentary rocks?
The main force is weight of overlying rocks , called overburden, which puts overburden pressure on sediments and make them compress and compacts
What cause rocks to change form and become metamorphic rocks?
heat and pressure
Which statements best describes the formation of diamonds?
The statement that best describes the formation of diamonds could be "Diamonds are formed by pressure, weight, and high temperature of overlying rocks."
Heat and pressure can cause some rocks to change into different types of rocks?
sedimentary rocks
Which type of rock forms due to the weight of overlying rocks?
Metamorphic
Which type of rock forms due to weight of the overlying rocks?
