Answer:
If two plates move away from each other then a continental rift will form.
Explanation:
There are three basic types of plate boundaries, convergent, divergent, and transform plate boundaries. All of them have their own characteristics and the boundaries can be between oceanic and oceanic, oceanic and continental, and continental and continental plates, and each type creates different landforms.
If there are two plates moving each other over land, then a continental rift will form. Basically, the two plates slowly move away from each other, opening a gap that is constantly widening, so over time, it grows into a rift valley. Over the course of millions of years, the continental rift or rift valley will get filled by oceanic water and physically separate the two landmasses. A perfect example of this is the divergent plate boundary between the Nubian and Somali plates which have created the rift valley cutting through the eastern part of Africa.
Well, i would say that: <span>because of large deposits of iron ore. they needed to provide there country at least with something, so that is why.
so the final is: </span><span>because of large deposits of iron ore.
hope that this helps you.
have a great day! =)</span>

Answer:Explanation:
DE is highly absorbent and will then suck the moisture away from the pest until it dies of dehydration. After coming in contact with the diatomaceous earth, fleas may die in as little as 4 hours, though it is recommended to leave the DE for up to 48 hours(2 day) to ensure its effectiveness.
It remains effective as long as it stays dry, and often takes a week or more to start killing insects. Since the insects may have laid eggs by then, leaving on the diatomaceous earth for several weeks will help prevent a rebound.
