The American alligator lives in swamps and lays eggs. The female American alligator builds a nest out of sticks, leaves, and mud,
and lays the eggs in the nest. Then, she covers them with more vegetation, and stays near the nest until the eggs hatch after about
65 days. Some individual alligators are able to build sturdier nests at better locations.
How does the trait of building better nests help American alligators survive and reproduce?
OA. The eggs require more time to develop in the nest.
OB. The nest allows the mother to have a place to rest.
OC. The nest draws more attention from predators and male alligators.
OD. The eggs are better protected from the weather by the nest.

is this a question? wassup

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
