Radioactive decay in the inner core of k40 U238 and Th232 cause the earths internal heat plus lithostatic pressure (pressure of the overlying rocks).
magma
"are places on the earth's surface where molten rock, gases, and ash from deep inside the earth are ejected."
No, igneous rocks can be formed both inside the Earth (intrusive or plutonic) and on the Earth's surface (extrusive or volcanic). Intrusive rocks form underground when magma cools slowly, while extrusive rocks form on the surface when lava cools rapidly.
Lava.
Molten rocks under the Earth's surface are called magma. When magma reaches the Earth's surface, it is then called lava.
The crust and part of the mantle is made of rocks and solids. The other layers under the earth are mostly composed of molten lava or semi-molten rocks.
The molten material deep inside Earth from which igneous rocks form is called _
When molten material from inside the Earth cools, it forms igneous rock. The type of igneous rock that forms depends on the rate of cooling and the mineral composition of the molten material. Fast cooling can result in fine-grained rocks like basalt, while slow cooling can create coarse-grained rocks like granite.
High temperatures inside the Earth can lead to the formation of molten rock, known as magma. This molten rock can rise to the surface and form volcanic activity, such as volcanic eruptions and lava flows. It can also form igneous rocks when it cools and solidifies.
The state of rocks and metals inside the Earth is determined by temperature and pressure. As you go deeper into the Earth, both temperature and pressure increase, causing rocks and metals to exist in different states such as solid or molten.
yes
Hot molten rocks from the interior of the earth are called magma when they are beneath the earth's surface and lava when they reach the surface through volcanic eruptions.
