Which statement best describes the formation of an intrusive igneous rock? here are the choices:
a. magma solidifies slowly, resulting in a coarse-grained texture.
b. magma solidifies slowly, resulting in a fine-grained texture.
c. magma solidifies rapidly, resulting in a glassy texture.
d. magma solidifies rapidly, resulting in a clastic texture

The correct answer is - A. Magma solidifies slowly, resulting in a coarse-grained texture.

The intrusive igneous rocks are forming when the magma solidifies very slowly, deep underground, under higher temperatures and pressures. All these conditions contribute to the coarse-grained structure to form on these types of rocks and have it as a trademark. These rocks are very hard rocks, with big density, their colors vary a lot but are more on the dark side usually. Some of them are diorite, granite, pegmatite...

the correct answer is d.) many new life-forms appeared, including most of the known types of invertebrates. hope this

it deviates because of the date.

explanation:

the international date line is an imaginary zig zag line on the surface of the earth roughly following the 180 degree meridian. crossing the date line causes the date to be changed exactly by one day. crossing the line from east to west , one loses a day . and from west to east, one gains a day.
