Erosion, weathering, and rock formation. They are made of pebbles or sand stuck together.
yes, all rocks can form from all others depending on pressure, etc
All rocks can form from sedimentary because the rock cycle is endless.
Yes, metamorphic rocks can be subjected to high temperatures and pressures which can cause them to melt and recrystallize into igneous rocks. This process is known as anatexis. Metamorphic rocks can also undergo weathering and erosion to form sedimentary rocks.
No.
No, while all rocks on Earth were molten at one point, most rock types do not form from magma. Rocks that form from magma or lava are igneous rocks. Most of the rocks at Earth's surface are sedimentary. These rocks form from the remains of rock that have been broken own into tiny pieces or dissolved in water. These components eventually settle, usually in a body of water, and are buried and turned to stone. Metamorphic rocks make up a third category. These form from rocks that have been altered under enormous heat and pressure while remaining solid.
No rocks have "Krystle's" - there is no such word as "Krystle's" and if there were you are using the "'" incorrectly. All rocks contain minerals, most of which are in Crystalline form.
No. Rocks can be classified into three general groups: Igneous rocks, which form from molten rock Sedimentary rocks, which form from broken-down rocks turned back into stone Metamorphic rocks, which form as rocks change due to heat and pressure without melting. Igneous rocks are further divided into intrusive rocks, which cool underground, and extrusive rocks, which cool above ground. Only extrusive igneous rocks are considered volcanic.
granite is all that i know of.
All types of rock can melt. Thus potentially ALL types of rocks can form a magma. Your question - asking for 3 types, is therefore meaningless.
Metamorphic rocks can form from both igneous and sedimentary rocks
Metamorphic rocks can form from both igneous and sedimentary rocks
Yes. All rocks are at some point in the rock cycle depending on its own composition and the environment it is in (it can be subject to weathering to form sedimentary rocks, high temperature and pressure to form metamorphic rocks, or melting and cooling to form igneous rocks)
