Answer:
hematite, also spelled haematite, heavy and relatively hard oxide mineral, ferric oxide (Fe2O3), that constitutes the most important iron ore because of its high iron content (70 percent) and its abundance.
Explanation:
<span>First we have to know what an "internal stimulus" is.
An "internal stimulus" is something INSIDE of us, that makes us want to do something.
Hunger is an example of an internal stimulus.
It comes from within us.
And it makes us want to eat.
So, since hunger is the stimulus,
an appropriate response would be to eat some food.
Does that make sense?</span>

Answer:
D) movement of the tectonic plates.
Explanation:
Lets understand first what convection is. It refers to the process through which denser material sinks and less dense material rises. This is because less dense material is more buoyant than denser one.
The earth is composed of water, rocks and air and all these things lower their density when there occurs an increase in their temperature.
So what happens when convection occurs in the upper mantle of earth, it raises the less dense material called magma in uprising direction, because of the extreme heat in the Earth’s core. When molten lava moves upwards it moves in a fashion of convection, but then it cools down and sinks again.
As the earth surface is made up of tectonic plates. Scientists believe that when convection occur in mantle layer, it causes the movement of plates, This movement can be away from, or towards each other. The movement of tectonic plates causes shifts continents, ocean basins, earthquakes and pushes up mountains.
So D is best option.
Hope it helps!
