What is fossils and what is igneous,sedimentary, metamorphic rocks
Answers
Description
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.
Description
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.
Description
Sedimentary rocks are types of rock that are formed by the deposition and subsequent cementation of mineral or organic particles on the floor of oceans or other bodies of water at the Earth's surface. Sedimentation is the collective name for processes that cause these particles to settle in place.
Description
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.
A fossil is a part of an animal that was trapped in a rock millions of years ago.
Igneous Rocks
Igneous Rocks are formed due to solidification of the hot magma that poses out from a volcano.
Metamorphic Rocks
Metamorphic Rocks form 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.
Sedimentary Rocks
Sedimentary Rocks are those that are formed by the deposition and subsequent cementation of minerals.
