Question

use the text to compare and contrast extrusive rocks and intrusive rocks. you may be familiar with the three main types of rocks: igneous, metamorphic, and sedimentary. but did you know that igneous rocks come in more than one type? intrusive and extrusive are the two kinds of igneous rocks. intrusive rocks are formed from hot magma deep inside the earths crust. in contrast, extrusive rocks are made from hot lava at the earths surface. since extrusive rocks form at the surface, they are exposed to air and water, which causes them to cool and solidify very quickly. they form so quickly, in fact, that they dont have time to form large crystals. but intrusive rocks solidify very slowly, because there is no air to cool the magma. therefore, unlike extrusive rocks, intrusive ones form large crystals and are quite coarse. granite is an excellent example of an intrusive rock, whereas basalt is a good example of an extrusive one. extrusive rocks intrusive rocks are types of igneous rocks are made from lava at the earths surface solidify slowly form large crystals basalt is an example

Explanation:

The text states that both extrusive and intrusive rocks are types of igneous rocks. Extrusive rocks are made from lava at the Earth's surface, cool and solidify quickly, don't form large crystals, and basalt is an example. Intrusive rocks are formed from magma deep in the Earth's crust, solidify slowly, form large crystals, and granite is an example.

Answer:

Extrusive rocks	Intrusive rocks
Are made from lava at the Earth's surface: Yes	Are made from lava at the Earth's surface: No
Solidify slowly: No	Solidify slowly: Yes
Form large crystals: No	Form large crystals: Yes
Basalt is an example: Yes	Basalt is an example: No
