What are the kinds of rocks?
All rocks are solid. Igneous, metamorphic, or sedimentary.
What type of rock is?
There are three major types of rocks: igneous, metamorphic, and sedimentary. Rocks are classified based on the process by which they were formed. Sedimentary rocks form from sand, dust, and tiny rock particles that are fused by water and extreme pressure over time. Igneous rocks form from cooled magma or lava; depending on how fast they were cooled and solidified, igneous rocks may or may not go through crystallization. Metamorphic rocks are rocks that changed from either sedimentary rocks, igneous ones, or other metamorphic rocks. These generally form from wind, water, or chemical erosion.
What are the different types of rock with how they form?
Igneous rocks are formed by the cooling of magma (molten rock underneath the Earth's surface) or lava (molten rock on the surface). Extrusive igneous are formed on top of the surface, while intrusive igneous and plutonic are formed beneath. Sedimentary rocks are formed by sediments being compacted and cemented. Sediments are small materials, either inorganic (broken of bits of rocks, sand, mud etc) or organic (shells, decaying life forms). Metamorphic rocks are rocks that have been physically or chemically changed by heat and/or pressure. This can be either contact or regional. Contact is when molten rocks comes close enough to a rock to change it, etc. Regional is metamorphism that occurs over a wide region usually by the force of plate tectonics.
Describe the changes that occur in the rock cycle.?
In the rock cycle, rocks change into differant types of rocks over time. For example, igneous rocks might break into sediments that form sedimentary rocks.
Igneous rock is also known as what?
Igneous rock (derived from the Latin word ignis meaning fire) is one of the three main rock types, the others being sedimentary and metamorphic rock. Igneous rock is formed through the cooling and solidification of magma or lava. Igneous rock may form with or without crystallization, either below the surface as intrusive(plutonic) rocks or on the surface as extrusive (volcanic) rocks. This magma can be derived from partial melts of pre-existing rocks in either a planet's mantle orcrust. Typically, the melting is caused by one or more of three processes: an increase in temperature, a decrease in pressure, or a change in composition. Over 700 types of igneous rocks have been described, most of them having formed beneath the surface of Earth's crust.
Explain how igneous rocks form?
Igneous rocks are one of the 3 main type of rocks, the others being sedimentary and metamorphic rocks. Igneous rocks are formed from the cooling of lava and magma. There are over 700 kinds of igneous rocks, and most are found beneath the surface of the Earth's crust.
How does igneous rocks form?
Igneous rocks forms when molten rock cools&becomes solid. Igneous rocks that originally formed at great depths can reach Earth's surface over time. Deep rocks may be raised closer to the surface when mountains are pushed up.At the same time , other process can wear away the rocks that cover the deeper rocks
What are Igneous rocks that formed beneath Earth's surface called?
Igneous rocks that are formed deep inside earth are called intrusive igneous rocks. These rocks are created when magma cools over millions of years inside earth. As it is cools, elements combine and form minerals. Intrusive igneous rocks are usually identified because they have visible crystals.

What four forces move the rocks through the rock cycle?
First a rock gets erupted within or on the Earth surface in the form of igneous rocks. Those are over time eroded away and deposited as sedimentary rocks. By subjecting these rocks to tremendous pressure and heat they metamorphose or change into metamorphic rocks which can eventually wind up in molten state and get re-introduced and erupt back as igneous rocks.

How do igneous rocks that form from cooling lava differ from igneous rocks that form from cooling magma?
The difference between the two lies in the mineral crystal size. Rocks that form from lava on the surface will cool quickly, with little time for crystal formation. Rocks that form from magma below the surface will cool slowly, resulting in larger mineral crystals. Chemically, they could be identical.
How do intrusive igneous rocks become visible in the surface of earth?
it easly wears away and can travel by magma streams or rivers or could wear away into particles called protons and gets blown away by the wind.it can then land somewhere to slowly collect more particles to form an igneous rock in a random place
