Answer:

The two subcategories of igneous rocks are intrusive and extrusive igneous rocks.

Explanation:

The igneous rocks are the rocks that form from cooling magma and lava. They are the base for the formation of the two other types of rocks. The igneous rocks are divided into two subcategories, intrusive and extrusive.

The intrusive igneous rocks are the ones that form from magma that didn't manage to come out on the surface but gradually cooled off into the crust. The extrusive igneous rocks are the ones that have formed from lava that cooled off and that has come out on the surface or very close to the surface.

Because the extrusive and intrusive rocks take different times to form because of the difference in temperature and pressure on the surface and deep into the crust, they have differences in their appearance. The most noticeable difference is that the intrusive igneous rocks have coarse grains, thus large and well-defined ones, while the extrusive ones have fine grains, thus very small and almost unnoticeable.

Norma-Jean [14]

Based on the fact that the single cell of the Amoeba can split in half, the correct answer is The student is correct; amoebas are probably alive because they have reproductive capabilities and create offspring through reproduction.

<h3>Why is the student correct about Amoebas?</h3><h3 />

An organism is considered to be alive due to various reasons and one of them is whether the organism has reproductive capabilities and can therefore reproduce and create offspring.

Even though the Amoeba is a unicellular organism, it can still reproduce asexually which means that it can reproduce without the need for another organism of its kind like it does when it splits itself in two.

Which of the following does not contribute to long-term climate change?
Wewaii [24]

Answer:

b. sunspot activity

Explanation:

  • As the sunspots are dark and cooler spots on the surface of the sun and they are formed due to a cycle of 11 years and don't directly impact the long term climate cycle of the onset earth as the rise and fall in the sea levels and the movement of the ice sheets and the tectonic upliftment are not caused by them and thus they are not responsible for the climatic changes on earth.
  • <u>Sun energy is needed d to keep the net active and with the presence of the sun the earth world has temperature extremes and no rotational motion thus long term climatic patterns are dependent on the planet's internal framework.</u>
