An igneous rock floats because air bubbles became trapped when molten material erupted from an underground volcano.

how else can this rock be accurately described? check all that apply

intrusive
extrusive
small crystals
cooled quickly
coarse texture

The answer are:

- Intrusive

- Coarse texture

Explanation:

Igneous rocks are those that form when magma cools and solidifies. Igneous rocks can be of two types depending on whether the cooling of magma occurs slowly or quickly and if it occurs on the surface of the earth's crust or inside. The type of igneous rock described in the question is an intrusive rock, which is formed from solidified magma in large masses inside the earth's crust, which cools slowly, allowing minerals to form large crystals ( thick texture).

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.

e) all of the above

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
