C
Explanation:
i would need more details but this seems like the answer
sorry if i am wrong
1. Peridotite
2. Basalt
3. Andesite
4. Rhyolite
Explanation:
The igneous rocks all have the same basis when it comes to their formation, but still many variations occur that determine their composition. The variations come from the factors such as the location where they have been formed, the composition of the magma/lava that formed them, the pressure they experienced etc.
This has led to the formation of four different groups of igneous rocks when it comes to their composition. One groups is the ultramafic, and a representative for this group is the peridotite. The mafic group is represented by the basalt. The intermediate group is represented by the andesite, and the felsic group is represented by the rhyolite.
It is relatively easy to distinguish these four groups by their appearance, as some have coarse-grained textures, while the others have fine-grained textures. The coarse-grained textures indicate intrusive rocks, while the fine-grained are indicator of extrusive rocks.
Answer:
Papau New Guinea is the eastern half of the Island of New Guinea and is independent from New Guinea
Explanation:
New Guinea is an island to the north of the Australian mainland, but south of the equator. Politically, the western half of the island comprises two provinces of Indonesia: Papua and West Papua. The eastern half forms the mainland of the country of Papua New Guinea
In Plate Tectonic Theory, the lithosphere is broken into tectonic plates, which undergo some large scale motions. The boundary regions between plates are aptly called plate boundaries. Based upon their motions with respect to one another, these plate boundaries are of three kinds: divergent, convergent, and transform.
The answer to this question is D.
Climate change is causing the Earth to gradually increase in temperature, this is causing the warming waters.
Coral has this beneficial relationship with this algae called zooxanthellae. The coral provides a home where the algae provides some nutrients. Zooxanthellae uses photosynthesis to get its own food (It's not getting any inside a coral polyp!)
When there is an increased amount of sunlight there is more photosynthesis occuring, which means more and more algae.
To disprove C, the great barrier reef is KNOWN for its biodiversity. Theres LOTS goin' on down there.
Hope this helps!
