Igneous rock forms from a. weathered rock particles. b. magma. c. evaporation of water. d. none of the above

b. magma. is the correct answer.

Explanation:

Igneous rock forms from magma.

Igneous rocks are formed by the cooling and solidification of molten magma or lava.

Igneous rocks are of two types

When the lava reaches the surface of the earth by volcanic eruptions the rocks formed by this process are called Extrusive Igneous rocks

Examples of extrusive igneous rocks are obsidian, volcanic ash, pumice, and cinders.

Examples of intrusive igneous rocks are granite, diorite, and gabbro.

primary succession occurs in essentially lifeless areas regions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunes, or rocks left from a retreating glacier. secondary succession occurs

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community
