CCC Stability and Change Liquid water has existed on Earth's surface for at least 4 billion years, even as the sun's energy output has continued to increase. The total area of continents (now 39% of Earth's surface) may have grown in size over Earth's history. Think about what you know about the albedos of land and water. Does an increase in land area explain why Earth's surface hasn't heated to a point that the ocean has boiled away? Why or why not?

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.

step-by-step explanation:

18.75 gallons

step-by-step explanation:

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
