The troposphere because it has half of all air in the Atmosphere
E is correct, that triangle is acute
A- Graph B shows exponential growth of a population.
Graph B is a type of exponential equation where y=a(b)^x
"a" is the initial value that intercepts the y-axis in the above equation.
"b" is the value that every value thereafter is growing (multiplying by). Note, if "b" is 1- your value is not growing (since it is staying at it's original 100%). If "b" is, for example 1.5 your value is growing by 50% each time (1 gives you your original 100%, and the .5 gives you an additional 50% on top of that).
"x" is your input, and here it is the exponent because you are multiplying "b" to the power of your input for each value.
<span>A weather front or front is a
narrow region between two air masses of different densities. The answer is
letter C. Because of the difference in density between warm and cold front, cold
air tends to go underneath the warmer air. It often creates the strongest winds
above the ground surface. This is caused due to the heat and mass transfer between
particles of air. They can be slowed down by the presence of mountains and
valleys. Cold air moves fast and the temperature around it can be felt as if
you are blown away due to its density. Whereas warm air moves slowly.</span>
