Answer:

False

Explanation:

Intrusions are not formed by lava from outside the earth's surface.

This statement invalidates the claim made in the sentence.

  • Intrusions are molten rocks that forms and crystallize within the earth surface.
  • Extrusions are molten rocks that reaches the earth surface.

Both originates from molten rocks within the earth surface that can be produced within the lithosphere or under the mantle.

Molten rocks, magma, that reaches the surface is called lava.
