what is a rock?how is it formed
Answers
Answer:
A rock is a solid made up of a bunch of different minerals. Rocks are generally not uniform or made up of exact structures that can be described by scientific formulas. Scientists generally classify rocks by how they were made or formed. There are three major types of rocks: Metamorphic, Igneous, and Sedimentary.
When soil and surface materials erode over time, they leave layers of sediments. Over long periods of time, layer upon layer of sediments form, putting intense pressure on the oldest layers. Under great pressure and heat, lower layers of sediments eventually turn into rocks.

Question:
What is a rock? How is it formed?
Answer:
A rock is a solid made up of a bunch of different minerals. Rocks are generally not uniform or made up of exact structures that can be described by scientific formulas. Scientists generally classify rocks by how they were made or formed. There are three kinds of rock: igneous, sedimentary, and metamorphic.
Igneous - A rock formed by the cooling and crystallization of magma (molten rock) at or below the Earth's surface.
Sedimentary - A rock formed as a result of the weathering process, either by compaction and cementation of rock mineral fragments, or the precipitation of dissolved minerals.
Metamorphic - A rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors. Conditions like these are found deep within the Earth or where tectonic plates meet.
