Answer:
igneous rock
Explanation:
There are three main kinds of rocks, sedimentary, metamorphic and igneous.
The igneous rocks are the ones that formed from a hot source like magma inside the soil, as it gets to the surface of the Earth it goes cooling. If it cools almost in the surface of the Earth then is consider a plutonic rock.
Plutonic Rocks have a big quantity of minerals, since they cool under a big pressure, these minerals get together forming a solid rock.
By passing the time the granites of minerals can be easily seen at naked eye, like the characteristics of these sample.
Oh, yeah? Then why'd you post this, hmm?
Answer:
Principle of faunal succession
Explanation:
Principle of faunal succession -
According to this theory , the layer of the sedimentary rocks have fossils of the flora and fauna .
Which helps to study the rocks regarding the ages and the types of specifies found at that time .
It is the best method to study about the ancient lives , which helps by determining the relative age of the rocks .
Even the law of superposition is used to determine the time and age of the sedimentary rocks .
Answer:
Overfishing is the removal of a species of fish from a body of water at a rate that the species cannot replenish, resulting in those species becoming underpopulated in that area.
