Question

Clouds dump around 100 billion gallons of water on rainforests each year. How much rain is evaporated from the rivers, lakes and surface of rainforests each year?

a. around 100 billion gallons
b. unable to tell from the information given
c. significantly less than 100 billion gallons
d. significantly more than 100 billion gallons

Answer 1

The correct answer is 'unable to tell from the information given' because there is no direct information linking the 100 billion gallons of rainfall to evaporation rates in rainforests, and the hydrological cycle depends on many variables.

Step-by-step explanation:

From the information provided, option unable to tell from the information given is the correct answer to the question about how much rain is evaporated from the rivers, lakes, and surface of rainforests each year. The details given focus on evaporation rates, the hydrological cycle, the annual rainfall in tropical rainforests, and the impact of factors such as deforestation on these rates. However, there is no specific information given that correlates the 100 billion gallons of water dumped by clouds directly to the amount that is evaporated from the rainforest surfaces each year. The hydrological cycle is complex and depends on numerous variables, including but not limited to, sunlight, temperature, vegetation, and geographical features.

Answer 2

b. unable to tell from the information given

Step-by-step explanation:

We have only been given the amount of water rainforests receives in a year. No other information has been given. So also, we cannot make any further assumption and deduction from the information provided to us. In order to know the amount of water evaporated in a year, we should have been given the rate of evaporation in the rainforest. We cannot deduce the amount of water evaporated from this data.
