When temperature and pressure change what can happen to the minerals and rocks?
They can change into coal
What can melt rocks without changing temperature when their confining pressure?
The process of partial melting can occur in rocks under high confining pressure, where the minerals in the rock start to melt without the overall temperature changing. This happens because the pressure lowers the melting point of the minerals. The supercritical fluids in Earth's mantle can also cause rocks to melt without a change in temperature under the high pressure conditions.
What happens to the speed of a wave of the medium temperature and pressure do not change?
remains constant
What happens to the pressure of gas when the volume is doubled and no change in Kelvin temperature?
According to Boyle's Law, when the volume of a gas is doubled with no change in Kelvin temperature, the pressure of the gas will be halved. This is because pressure and volume are inversely proportional in a gas at constant temperature.
Does an increase in pressure make magma cool?
Pressure does not change the temperature of rocks, but it does change the melting point. A rock that is under a lot of pressure, even if it is very hot, will stay solid, even if that same rock at the same temperature under lower pressure would be melted. This happens because intense pressure can hold the structure of the minerals together more easily, in a more solid form.So, with an increase in pressure, the melting point of a rock also increases.
When does Boyle's law happen?
Boyles law "happens" when the temperature is held constant and the volume and pressure change.
Can a minerals density change?
A mineral's density remains constant unless there is a change in its composition or structure. Factors such as pressure, temperature, and chemical reactions can alter a mineral's density.
Why do minerals only occur in metamorphic rocks?
because of the metamorphism when temperature and pressure inside earths crust change that were present in the rock when it formed
When temperature and pressure change what can happen to the mineral in rocks?
When temperature and pressure change, minerals in rocks can undergo recrystallization or phase transitions, leading to changes in their crystal structure and composition. This process can result in the formation of new minerals or the growth of existing ones to accommodate the new environmental conditions. Conversely, if the changes are too extreme, minerals may become unstable and break down into new phases or even melt.
What condition change igneous sedimentary to metamorphic rock?
The conditions that change igneous or sedimentary rock into metamorphic rock include high temperature, high pressure, and the presence of chemically active fluids. These conditions cause the minerals in the original rock to recrystallize, forming new minerals and textures characteristic of metamorphic rocks.
What change has occurred to metamorphic rock?
Metamorphic rock has undergone changes in temperature, pressure, or chemical composition, causing it to recrystallize and form new minerals.
How do high temperatures and pressures cause fossils to change into minerals or rocks to change their nature?
The changes take place because of recrystallization or realignment of existing minerals, or creation of minerals from existing assemblages that that can only be formed under certain specific ranges of temperature or pressure.
