Why do you think scientists want to be able to forecast space weather?

Scientists would most likely want to forecast space weather in order to know if it is safe for not only to lift off into outer space, but to be able to help astronauts in any case of emergency if something were to happen in the future.

Such as debris of small rocks that could pass by, so then astronauts would have to stay in the shuttle. To be protected from it.

In any case, scientists want to forecast the weather in outer space in order to protect astronauts, from any incoming dangers.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).   so the answer is a.

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.
