Arock is found in an area that once had an active volcano and has since been affected by erosion. the rock has individual black and white crystals that are easy to see. which other description fits the rock? fine texture cooled quickly exposed to air and water cooled inside the volcano

The answer is D - cooled inside the volcano because its not A or B  or C texture because its not reasonable

D- cooled inside the volcano

Explanation:

A is incorrect because rocks that cool outside a volcano (from lava) have small crystals, in other words, a fine texture

B is incorrect because rocks that form inside a volcano don't cool quickly

C is incorrect because when lava is exposed to air and water, it cools quickly

D is correct because the crystals are large, and the crystals can only be large if they cooled inside the volcano (from magma).

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.

the answer is d. chordata
