When magma reaches the exterior of the Earth's crust is becomes?
When magma reaches the exterior of the Earth's crust, it solidifies and cools, forming igneous rocks such as basalt or granite. This process can occur both above ground, creating volcanic rocks, or below ground, forming intrusive igneous rocks.
Where does magma cool?
Magma cools and solidifies either underground within the Earth's crust, forming intrusive igneous rocks like granite, or when it erupts onto the Earth's surface as lava and cools quickly, forming extrusive igneous rocks like basalt.
About how many rock forming minerals make up most of the rocks Earth crust?
Most of the Earth's crust is primarily composed of about 20 rock-forming minerals. Among these, the most abundant are feldspar, quartz, mica, amphibole, and pyroxene, which are crucial in forming igneous, sedimentary, and metamorphic rocks. These minerals account for the vast majority of the Earth's crustal composition, with feldspar alone making up nearly 60% of the crust.
Does intrusive have lava or magma?
Intrusive igneous rocks form when magma cools below the Earth's surface. Thus, intrusive rocks are associated with magma. Lava, on the other hand, is molten rock that flows onto the Earth's surface, forming extrusive igneous rocks.
How many rocks are underground?
It is impossible to determine the exact number of rocks underground as the amount can vary greatly depending on the location and geological conditions. Rocks are constantly forming and shifting in the Earth's crust, so the number is always changing.
Difference of lunar rocks and earth rocks?
Lunar rocks are those forming the Moon - as the word 'lunar' says. Earth rocks are formed on Earth - but the rock forming the Moon is also a constituent of the Earth.
What could still exist if earth stopped spinning?
rocks, the other planents

When melted rock cools or hardens in or under earth surface it forms to what?
When melted rock cools and hardens in or under the Earth's surface, it forms igneous rock. This process can happen above ground, forming volcanic rocks, or below ground, forming intrusive rocks.

What do rock from Earth and rocks from the Moon have in common?
Many of the rocks of the Moon are described as breccias, that is they are formed from pieces of older rocks. Various types of breccia occur on Earth too, for instance in volcanic regions. Basalt is also common on the Moon, and this is also true of Earth. The Moon has lots of the mineral feldspar, which is also the commonest of the Earth rock forming minerals.
Why do think that the earth was created?
Earth was created as a result of the big bang. Debris from rocks, dust and ice as a result of the bang were squeezed together by gravity, forming spherical planets.

Which type of rock is produced by the cooling and solidification of molten rock?
Igneous rock is produced by the cooling and solidification of molten rock. This process can occur both beneath the Earth's surface, forming intrusive igneous rocks, and at the surface, forming extrusive igneous rocks.
How many rock forming minerals make up most of the rocks Earth crust?
Most of the Earth's crust is primarily composed of about 20 rock-forming minerals. Among these, the most abundant are feldspar, quartz, mica, amphibole, and pyroxene. These minerals are essential in the formation of igneous, metamorphic, and sedimentary rocks that constitute the crust. Together, they play a crucial role in the geological processes that shape the Earth's surface.
