<span>The correct answer to this question is B - the two key questions in geography are intended to obtain certain factual information. Whilst the other possible questions given as answers for this question, such as 'why are they going' give indefinite, opinion-based answers, only answer B. Which birds are migrating would give a definite answer.</span>
Explanation:
The "doldrums" is a descriptive adjective for the corridor from around Earth closer to the equator when ships can become stuck in windless seas. In the horse elevations, where even the air moves down to towards the Earth's surface, the increasing jet stream eventually subsides.
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.
Answer:
The high islands of the Pacific were formed by seismic activity whereas the low islands of the Pacific were formed by coral growth. Continental islands and oceanic islands were formed by volcanic activity.
High islands often have fertile soils and lush rainforests. In contrast, low islands are often less fertile than high islands. Some low islands lack freshwater sources.
