What determines the type of igneous rock that forms from magma? a. The heat and pressure the magma is exposed to b. Whether the
OLEGan [10]

Answer:

c. Magma composition and cooling rate.

Explanation:

A rock cycle can be defined as a concept used to describe the continuous process that leads to a rock's creation, formation, transformation from one form to another, destruction and reformation over a specific period of time. The natural phenomenons that influences the rock cycle are weathering, plate tectonic activity, erosion, etc.

Basically, the three (3) main types of rocks are; metamorphic rock, sedimentary rock and igneous rock.

All igneous rocks are produced from magma (lava) and formed at the Earth’s surface, thereby, causing them to have a coarse texture and dark colors.

Generally, the cooling and solidification of magma (lava) leads to the formation of an igneous rock, either when the melted rock is still inside the continental crust of the Earth or at volcanoes on the Earth's surface.

Hence, magma composition and cooling rate determines the type of igneous rock that forms from magma. Some examples of an igneous rock are granite, obsidian, tuff, basalt, rhyolite, andesite, pegmatite, dacite, scoria, pumice, etc.

At which type of plate boundary do tectonic plates slide past each other?
melamori03 [73]
The answer would be conservative plate boundaries.

They occur where plates slide past each other in opposite directions, or in the same direction but at different speeds. Friction is eventually overcome and the plates slip past in a sudden movement. The shockwaves created produce an earthquake.

I hope this helped and is correct! :)
