How could a scientific theory be changed?
Scientific theories are made to explain phenomena. Newton made his laws of motion to explain what he observed in the behavior of accelerating objects. When his law failed to explain the motion of very massive objects in situations of very large forces and speeds (such as the orbit of Mercury about the sun) the theory had to be modified slightly to explain the discrepancies. In this case this was done by Einstein's correction due to special relativity. The correction for the orbit of Mecury amounts to a movement of 0.5 seconds of arc per year in the nodes of the orbit.
When light travels 1.86X10 to the fifth power miles in 1 second how far does light travel in one year explain your answer?
light travels one light year in one years timeokay so whoever wrote this above is a retard, and light travels 6 trillion miles in one year, there is 525,600 minutes in a year, times that by 60, then do your 1.86X10 to the fifth and there you go
What are the steps in the pressure-flow hypothesis?
The pressure-flow hypothesis is a year-round ordeal. There are two major stops in this process. The "source" is also known as the photosynthesis cells. The "sink" is a place to store excess sugars. An example of a "sink" would be the actual carrot in a carrot plant. Once all of the leaves die, the plant stores the glucose in the carrot. In the pressure-flow hypothesis, sugars are being made in the photosynthesis cells. Once it comes to the time of year that we call fall, the plant's leaves begin to die. The plant responds to this situation by sending its extra sugars from the source to the sink (which is usually its roots). After the fall and winter, during our spring, the plant sends the sugars back up the xylem tubes, which brings them to the leaves. Inside the leaves, there are the photosynthesis cells. This is the point at which the whole process starts again.
How do you explain to an 8 year old how waves are formed?
When the sea travels towards the coast, the sea bed gets shallower - causing the front edge of the wave to slow down. The water at the back of the wave is moving faster than the front, causing the wave to 'rear up' into the classic white foam appearance.

Why does a young dog float but and older dog sink?
For the same reason teenagers can float and 80-year olds can't. Older dogs just don't have the energy.
Explain the fact that the temperature of the ocean at great depth is very constant the year round at the temperature of about 4C?
Because water is densest at 4C, so it will sink to the bottom of the ocean.
What year did Blackbeards ship sink?

What is Pop?
The word "Pop" is a soft drink or soda. It is called this because the bubbles caused by the oxygen added with water and sugar, makes a popping noise. For example, if you put a raisin in Sprite, it will sink to the bottom, float to the top, sink to the bottom, float to the top. This probably isn't the most technicle answer, probably because it is written by an 11 year old, but it's good enough :)
