Complete question:
1. Which of the following is true of the Trade Winds?
A They are diverging winds in the vicinity of the equator replacing sinking air.
B They are converging winds as a result of the coming together of the two westerlies.
C They are variable winds that move west to east in the mid latitudes.
D They are converging winds around the Sub-tropical High out of the sinking air.
E They are converging winds in the vicinity of the equator at the surface, replacing the rising air.
Answer:
E They are converging winds in the vicinity of the equator at the surface, replacing the rising air.
Explanation:
Trade winds are prevailing winds that flows in the earth equatorial region. The trade winds are persistent wind that blows from east to west. The trade wind have been used by captain and sailor to navigate across the world ocean. The trade winds are much stronger and consistent over the ocean than over the land. This wind is also characterized by great constancy in direction and to an extent speed .
Trade wind also assisted to promote trade between continents. The wind established trade route across the Atlantic and pacific ocean.
Trade wind converge in the vicinity of the equator at the surface displacing the rising air.
The answer is; Atmospheric circulation patterns keep the temperature of an area constant.
The atmospheric circulation does not keep the temperatures in an area constant, however, they regulate temperatures through convection currents. Hot air rises as cold air mass sinks to replace the rising hot less dense air. These currents transfer energy around the globe and prevent one area from overheating.
Answer:
The Ring of Fire, also referred to as the Circum-Pacific Belt, is a path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes.
Answer:
The length of the third side is 2.
Explanation:
According to figure, we have a right triangle. The missing length can be determined by Pythagorean Theorem:
(1)
Where:
- Hypotenuse.
, 
- Legs.
If we know that 
and 
, then the missing length is:
(2)
The length of the third side is 2.
Answer: is constant
Explanation:
In order to analyze the velocity of the stars within a galaxy, the <u>galaxy rotation curves</u> (developed by the American astronomer Vera Rubin) are used. These graphs are elaborated as a scatter diagram in which the orbital velocity of the stars present in a galaxy is represented on the Y axis and the distance of these stars to the center of the galaxy on the X axis.
Thanks to this diagram, it has been possible to observe a characteristic behavior in the rotation speed of the stars (and gas) present in the galaxies, which differs from the rules of the orbital movement of the planetary systems postulated by Newton and Kepler.
This means that in these galaxy rotation curves it has been observed that the rotation speed of stars and gas is "constant", regardless of the distance to the center of the galaxy. This discrepancy and these results were then used to demonstrate the existence of dark matter in the universe.
