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.

yKpoI14uk [10]
In this case, the protozoa will be in category B - animal-like protist.

Animals consume other living organisms to obtain energy. Archaea and bacteria are a high level classification of different kinds of microorganisms that include many different subtypes. So these are not appropriate answers as they are not specific enough. Plant-like protists can photosynthesize which these protozoans cannot. Fungus does have similarities with animals in that it consumes living tissue to survive, however animal-like protist is the best fit for this questions.
