Metamorphism occurs deep within the Earth, often beneath mountain ranges, where rocks are subjected to high heat and pressure, transforming them into metamorphic rock. Magma is molten rock that forms deep inside the Earth's crust, where temperatures and pressures are high enough to melt rocks. Biological weathering happens when plants or animals cause rocks or structures to break down. The tree roots are pushing into the cracks, causing the sidewalk to break. During metamorphism, minerals within a rock realign themselves into new patterns due to the pressure. This is why metamorphic rocks often have a layered or banded texture. As the construction workers dig deeper, the rocks experience more heat and pressure, leading to metamorphism, which makes them harder and more compact. Chemical weathering occurs when rocks are altered through chemical reactions. Rust forms on iron due to oxidation, which is a classic example of chemical weathering. Rocks that are buried deep beneath the Earth's surface, especially near tectonic plate boundaries, can be transformed into metamorphic rocks by heat and pressure. Magma is less dense than the solid rock around it, so it rises toward the surface, sometimes erupting through volcanoes. The rocks near the Earth's surface don't experience enough heat and pressure to undergo significant changes, unlike those buried deeper underground. Magma is what we call molten rock beneath the Earth’s surface. When it reaches the surface during a volcanic eruption, it’s called lava. Metamorphic rocks typically have a foliated or layered appearance because of the pressure they experience deep within the Earth. Limestone can change into marble through a process called metamorphism, which involves exposure to high heat and pressure deep within the Earth. The heat inside the Earth is largely due to radioactive decay, which releases energy and heats up the surrounding rocks. This process keeps the Earth's interior very hot. Rocks that are buried deep under the Earth's surface are subjected to high temperatures and pressures, which cause them to change into metamorphic rocks. Lava from a volcanic eruption cools and solidifies into igneous rock. This process creates the solid rock formations we see near volcanoes. Igneous rocks form when molten rock (magma or lava) cools and solidifies. If it cools on the Earth's surface after a volcanic eruption, it forms an igneous rock. When rocks are subjected to intense pressure but not enough heat to melt, their texture changes. This pressure causes the minerals to realign, creating a layered or banded texture. Mechanical weathering occurs when physical forces break down rocks into smaller pieces. In this case, the driveway is cracking due to freezing and thawing, which is a common form of mechanical weathering. The Earth's core is primarily made up of iron and nickel. These metals are responsible for the intense heat and also help generate the Earth's magnetic field. Limestone can turn into marble when it is exposed to high temperatures and pressures deep underground. This is an example of how metamorphism works. Read more
