What else can I help you with?
What rock is formed when sandstone is exposed to heat and pressure?
Igneous rocks-after having the chance to cool down after a melt (metamorphic rocks need pressure as well)
What region of the earths interior does the heat increase to the point that rocks can begin to melt?
The heat increases to the point that rocks can begin to melt in the region known as the mantle. This layer lies beneath the Earth's crust and is composed of solid rock, but under high temperatures and pressure, some rocks can melt and form magma.
Which environmental factors cause solid rock to melt?
High temperatures, high pressure, and the presence of water can cause solid rock to melt. As temperatures and pressures increase within the Earth's crust and mantle, rocks can begin to melt and form magma. The presence of water lowers the melting point of rock by aiding in the breakdown of minerals.
How are pressure and heat involved in melting rock in the mantle?
Pressure and heat in the mantle cause the rocks to become ductile and start deforming. As pressure decreases and heat increases due to the rising of magma, the rocks reach their melting point, allowing them to melt. This melted rock can then rise to the surface as magma and form igneous rocks.
If the heat and pressure inside earth cause a rock to melt what material would be formed?
If heat and pressure inside the Earth cause a rock to melt, the resulting material would be magma. When magma cools and solidifies, it can form igneous rock. The composition of the magma depends on the original rock material and the conditions under which it melted.
What rock is it when it experiences heat and pressure and does not melt?
Metamorphic rock
What rock is formed when sandstone is exposed to heat and pressure?
Igneous rocks-after having the chance to cool down after a melt (metamorphic rocks need pressure as well)
How does igneous rock change to metamorphic rock?
Metamorphic rock which is exposed to increasing heat and pressure from various sources can eventually melt. If this melt then solidifies, it has become igneous rock.
How does metamorphic change to igneous?
Metamorphic rock which is exposed to increasing heat and pressure from various sources can eventually melt. If this melt then solidifies, it has become igneous rock.
What three things control whether or not a rock will melt?
temperature, pressure, and fluid
What type of rock does not melt in high pressures?
No rock would melt because of high pressure. High pressure inhibits phase transformations like solid --> liquid or liquid --> gaseous as you may experience when you use a pressure cooker. It is the elevated temperature that does the trick.
How does decreasing the pressure of the rock affect the temperature at which it melts?
Decreasing pressure lowers the melting point of rocks because it reduces the confining pressure that keeps the rock in a solid state. As pressure decreases, the rock requires less energy to overcome the intermolecular forces holding its crystal lattice together, allowing it to melt at a lower temperature.
What happens to the pressure of the earth as depth below the surface increases?
the pressure decreases the pressure increases
What region of the earths interior does the heat increase to the point that rocks can begin to melt?
The heat increases to the point that rocks can begin to melt in the region known as the mantle. This layer lies beneath the Earth's crust and is composed of solid rock, but under high temperatures and pressure, some rocks can melt and form magma.
Rocks experience Greater heat and pressure what type of rock will they turn into if they do not melt?
metamorphic
What happens to rock when it is exposed to very high temperature?
Rock exposed to very high temperature and pressure will soften or melt.
Which environmental factors cause solid rock to melt?
High temperatures, high pressure, and the presence of water can cause solid rock to melt. As temperatures and pressures increase within the Earth's crust and mantle, rocks can begin to melt and form magma. The presence of water lowers the melting point of rock by aiding in the breakdown of minerals.
