Question

use the text to compare and contrast intrusive rocks and extrusive 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. 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 intrusive and extrusive rocks are types of igneous rocks. Intrusive rocks form from magma deep in the Earth's crust, solidify slowly, form large crystals, and granite is an example. Extrusive rocks are made from lava at the Earth's surface, solidify quickly, don't form large crystals, and basalt is an example.

Answer:

Are types of igneous rocks: Intrusive rocks - √, Extrusive rocks - √
Are made from lava at the Earth's surface: Intrusive rocks - ×, Extrusive rocks - √
Solidify slowly: Intrusive rocks - √, Extrusive rocks - ×
Form large crystals: Intrusive rocks - √, Extrusive rocks - ×
Basalt is an example: Intrusive rocks - ×, Extrusive rocks - √
