The three main types of rocks are:

1. Igneous rock
2. Sedimentary rock
3. Metamorphic rock

They are classsified by their formation :

Igneous rock- This type of rock is formed due to volcanic activities, and under this type of rock, it is seperated into volcanic rock and plutonic rock.

Volcanic rock is also called intrusive igneous rock, where the magma filled the cracks below surface and cools down without meeting the air. One of the example if this kind of rock is granite.

Plutonic rock is also known as extrusive igneous rock where volcanic eruption occurs and the lava cools down after being exposed to the air. One of the example is tuff.

Sedimentary rock- These kind of rocks are formed due to the accumulation of sediments overtime. Rocks are also divided into two types under this catagory, namely clastic and non-clastic sedimentary rock.

Cladtic sedimentary rock - It is where the particles of sediments gets compacted due to accumulation, and the rock is usually coarse grained with different size of particles, for example, breccia.

Non-clastic on the other hand, are formed by organic substance that existed for a very long time to become rock, for example, coal is a kind of rock that is formed by organic substances under million years of accumulation. It is posible that fossil will be found.

Metamorphic rock- These type of rocks under goes extreme high temperature or compaction to form a new kind of rock from their parent rock. For instance, igneous rock will turn into marble under high temperature.

Hope it helps!

Answer:

Well, most transportation methods cause carbon dioxide to go into our atmosphere. Using hairspray is also another way. Because of the high levels of Carbon Dioxide in our atmosphere, global warming has risen (if that’s a word :D). Due to global warming ice in Antartica is melting and the Polar bears are in danger (sadly). Now I can’t tell you anymore about this topic because I don’t know anything about it (I haven’t learned anything else yet) I hope this helped, and if you knew this information I’m really sorry....Have a great day!

An adaptive trait: (mark all that apply)
snow_tiger [21]

Answer:

[a] varies in its characteristics according to local environmental circumstances

[b] becomes common within a species through natural selection

[d] tends to promote the well being of an organism in its natural or social environment

Explanation:

The adaptive traits in the living organisms have a simple basic role, that is to make the organism better suited for survival in its environment. The adaptive traits come in all sorts of different shapes, be it some that are manifested in the physical appearance or in the behavior of the organisms. Adaptive traits can be increased speed, prolonged neck, living in a groups, developing thorns and many more. This type of traits occur when the organisms face increased competition or when the environment in which they live starts to change, so in order for them to survive, they start to develop traits that will make them better suited for the new conditions and more competitive. The main principle through which the adaptive traits are transferred and rapidly increase in a population is through natural selection, as the organisms choose the ones that have advantageous traits for their mates, while they live aside the others.

How does human population affect wildlife?
ki77a [65]

The human population affects wildlife by causing the change of the wildlife.

<h3>How does human population affect wildlife?</h3>

Human population affects wildlife by causing changes or reduction of habitat so that it automatically reduces the population of animals and plants in the wild. There are lots of cases of poaching and over-exploitation of land that ultimately bring negative consequences, namely habitat destruction, animal extinction, which ends in ecosystem damage. For example, the wildlife change was occured when the various wild animals lose habitat because their original habitat has been shifted due to land exploitation.

In conclusion, the human population affects wildlife by causing the change of the wildlife.
