erosion
and weathering
Eventually, in 500 to 1000 years, Old Harry (a chalk stack) will be weathered by the sea and erode. Eventually he will become a low or subsurface bench. The chalk rock band extends for some distance toward the Isle of Wight, where the formation has similarly been weathered into the Needles and the gravel bars known as the Shingles.
A large red kangaroo is sometimes referred to as "big red" due to its reddish coat. Kangaroos have been known to ingest small rocks to help grind up fibrous plant material in their stomachs as part of their digestive process.
Copper is actually an element, although it is present in rocks as a mineral. Physically, it's a metal mostly used for the conduction of electricity. As for other rocks, granite and basalt are igneous rocks, as in they were formed straight from a flow of lava. They will be generally of one colour and are not easy to break. Sedimentary rocks include limestone, sandstone, and other softer rocks. They are basically layers of mud that have hardened and compressed into rock over millions of years. You can find lots of fossils in sedimentary rocks. Beds of sedimentary rock will look like many layers sandwiched on top of each other and should be fairly brittle and easy to break. Metamorphic rock is sedimentary rock that has fused and reformed into "igneous" or solid rock because of heat, pressure and time. The sedimentary rock was heated under the surface of the earth, re-fused into a solid mass, and then cooled. Some rocks will have different coloured bands around them, this is a good indication of metamorphic process.
Intrusions refer to magma that solidifies below the Earth's surface, forming igneous rocks like granite. Extrusions occur when magma reaches the surface and cools quickly, creating volcanic rocks like basalt. Both processes contribute to the formation of different types of igneous rocks in Earth's crust.
Lichen is a symbiotic relationship between a fungus and algae or cyanobacteria. They are commonly found on rocks, tree bark, and soil, and help in nutrient cycling and soil formation. Lichens are sensitive to pollution and changes in the environment, making them important indicators of ecosystem health.

erosion
Weathering is the process that changes rocks into soil, sand, and sediment through physical, chemical, or biological means. It involves the breakdown and alteration of rocks at or near the Earth's surface over time.
The process in which rocks first bend and then break is called deformation. Deformation occurs when rocks experience stress, which can be caused by tectonic forces, pressure, or temperature changes. Initially, rocks may bend or fold under this stress, but if the stress is too great, the rocks can eventually break or fracture.
The process is referred to as metamorphism.
The process is called the rock cycle. It involves the continuous transformation of rocks through processes such as weathering, erosion, deposition, melting, and cooling in the Earth's crust and mantle over millions of years. These processes result in the formation of different types of rocks, including sedimentary, igneous, and metamorphic rocks.
Erosion occurs when rocks and soil are gradually worn away by natural forces like water, wind, or ice. This process can create changes in landscapes over time by moving and shaping sediments.

The Rock cycle
Weathering is the process of breaking down rocks into smaller pieces through physical or chemical means. This term is used because the rocks are gradually "worn down" by the elements of weather, such as rain, wind, and temperature changes. Over time, these weathering forces can cause rocks to crumble and erode.
Answering "What process changes igneous rocks into metamorphic types?"Igneous rocks convert into metamorphic due to extreme pressure and heat, which can come from magma/lava or the movement of tectonic plates. For example, the igneous rock basalt eventually turns into the metamorphic rock granulite.
