A gravel covered plain is called a Reg. A reg is a desert basin where the sand has been blown away leaving a gravel covered plain.
To graph this inequality, start with an open dot on -2.
We use an open dot because n is
greater than -2 but n is not equal to -2.
Next we draw an arrow to the right
to represent all numbers greater than -2.
I have graphed this inequality below too.
The graph below is my own work.
This should correspond to the first answer choice.
The two factors, Temperature and Pressure, have the greatest influence on the state of each of Earth's layers.
Hope I helped!
Explanation:
1-true
2-false (mainly aztecs used this technique)
3-true
4-true
5-false (we don't see slavery like we used to so false)
6-false (1808-1826 is when they started to become independent)
(hope this helps. I would say research 2 and 5 if you still want better answer. Have a great day!)
