The sky is blue because blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.
Answer:
1. There is enough DNA in the average person’s body to stretch from the sun to Pluto and back — 17 times.
2. The average human body carries ten times more bacterial cells than human cells.
3. It takes a photon up to 40,000 years to travel from the core of the sun to its surface, but only 8 minutes to travel the rest of the way to Earth.
4. At over 2,000 kilometers long, The Great Barrier Reef is the largest living structure on Earth.
5. There are 8 times as many atoms in a teaspoonful of water as there are teaspoonfuls of water in the Atlantic ocean.

Answer:
b. False
Explanation:
The trenches are not physical features that occur on places where there are subduction zones between the tectonic plates, but they do not appear on places where there are divergent plate boundaries. The trenches are simply very deep, narrow, ocean beds, that have very steep sides.
The divergent boundaries are the opposite boundaries from where the trenches occur. These boundaries occur between tectonic plates that move away from each other. The typical physical feature at this type of plate boundaries are the mid-ocean ridges (if it occurs in an ocean), or the rift valleys (if it occurs on land).
This type of boundary produces new crust on Earth, and they also can split a tectonic plate into two separate plates, or even give rise to a new continent.
The answer would be (B) Mediterranean. The Mediterranean climate stays between 60 and 30 degrees year round, and rarely dips below freezing. We can rule out tundra because it says below freezing year round. We can also rule out the highlands because the further up in elevation you go, the colder it gets. And finally, we can rule out the humid continental because its seasons are polar opposites. The humid continental has hot summers and freezing cold winters.
(Hope this helps!)
