Which of the following is not true of volcanoes?

heat within earth generates magma or molten rock
volcanoes are clustered along boundaries between tectonic plates
the chemistry of the magma/lava determines its texture and therefore the type of landform it builds.
if magma reaches the surface and erupts, a volcano is formed
volcanic eruptions are almost always followed immediately by earthquakes

The chemistry of the magma/lava determines its texture and therefore the type of landform it builds.

Explanation:

All the processes related to the formation of a volcano which is given here is evidence of the formation process of lava and magma deep inside the earth. Due to the heat inside the earth, the lava and magma are pushed upwards due to interaction with the molten rocks. Volcano thus is clustered along the boundaries of variou fault lines and between the tectonic plate or slabs. A true volcano will be formed when the erupted magma is thrown with underlying pressure and is forced upwards with gas and ashes. Volcanic eruptions are made not necessary be triggered due top an earthquake it may be triggered due to sudden changes in the ground below or movement of slabs and artificial causes like the man-made phenomena.

Iwould say d. eye contact and body language because you aren’t using any spoken communication. hope this : )
