Alaccolith is an example of a(n) rock (one of the two main igneous rock groups).

Intrusive igneous rocks

Explanation:

Intrusive igneous rocks are formed when magma cools and solidifies, which results in the formation of large crystal beneath the crust of the planet.

The cooling of the magma can be fast or slow, which determines the texture and color of Intrusive rocks.

Intrusive rocks are classified based on shape and size.

laccoliths are formed by the Intrusive rocks on the land.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
