Answer:
D. Above the Arctic Circle
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.
Many people believe that the temperature becomes lower in winters and higher in summers because the Earth is closer to the sun in summer and farther from the sun in winter. In fact, the Earth is farthest from the sun in July and is closest to the sun in January. The main reason behind these temperature changes in different seasons is because the earth's axis is tilted. It is all about the tilt of the Earth's axis.
EARTH CORE IS VERY HOT, VERY DENSE CENTER OF OUR PLANET
Africa is the continent that has the most countries through which the Equator passes. In fact, 7 out of the 13 countries in the world through which the Equator passes are in Africa. From west to east they are in this order, Sao Tome and Principe, Gabon, Republic of the Congo, Democratic Republic of the Congo, Uganda, Kenya, and Somalia. The Equator is an imaginary line invented by the humans for their own purposes. It basically is the line that separates the Earth into two equal parts horizontally, or rather into Northern Hemisphere and Southern Hemisphere. The Equator has latitude of 0 degrees, and it is the starting point from which the latitude is measured both north and south. This part of Africa is characterized with warm and wet climate, with the temperatures being constant throughout the whole year and have only few degrees of change, resulting in constant summer. The landscape is covered with dense tropical vegetation, and there's enormous amount of species that live in this area.
