Question

define the following terms fossils, igneous rocks,sedimentary rocks,metamorphic rocks

Answer 1

Igneous rock is formed when magma or lava from volcanoes cools. Examples include basalt and granite. ... Some sedimentary rocks contain fossils (bones or shells of living things that were buried long ago and have turned to stone). Metamorphic rocks are formed when other rocks are changed due to heat or pressure

Answer 2

Answer:

fossils:A fossil is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood, oil, coal, and DNA remnants.

igneous rocks:Igneous rock, or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava. The magma can be derived from partial melts of existing rocks in either a planet's mantle or crust

sedimentary rocks:

Sedimentary rocks are types of rock that are formed by the accumulation or deposition of small particles and subsequent cementation of mineral or organic particles on the floor of oceans or other bodies of water at the Earth's surface.

metamorphic rocks:Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means "change in form". The original rock is subjected to heat and pressure, causing profound physical or chemical change. The protolith may be a sedimentary, igneous, or existing metamorphic rock.
