The dwarf planet Pluto is located where?
in the Kuiper Belt |
|
outside the solar system |
|
between the orbits of Jupiter and Saturn |
|
in the asteroid belt |
The Kuiper Belt is similar to the asteroid belt but much larger. Extending beyond the orbit of Neptune, it contains objects composed mostly of frozen methane, ammonia, and water. Most notably, the Kuiper Belt is home to Pluto, a dwarf planet that, until a 2006 reclassification, was considered the ninth planet of the solar system.
What type of cloud is responsible for fog?
cumulonimbus |
|
stratus |
|
cumulus |
|
cirrus |
Clouds are categorized based on their shape, size, and altitude. Stratus clouds are low-altitude clouds characterized by horizontal layering with a broad flat base. When stratus clouds occur on the ground the result is fog.
What part of the brain is responsible for for balance, movement, and muscle coordination?
brainstem |
|
cerebellum |
|
cerebrum |
|
medulla |
The cerebellum is a large cluster of nerves at the base of the brain that's responsible for balance, movement, and muscle coordination.
50°F is how many °C?
122 |
|
-10 |
|
58 |
|
10 |
The formula to convert from F° to C° is:
\(C° = {5 \over 9} (F° - 32)\)
plugging in our values gives:
\(C° = {5 \over 9} (50 - 32)\)
\(C° = {5 \over 9} (18)\)
\(C° = {90 \over 9}\)
\(C° = 10\)
Earth's troposphere layer is which of the following?
coldest |
|
closest to the surface |
|
hottest |
|
farthest from the surface |
The Earth's atmosphere has several layers starting with the troposphere which is closest in proximity to the surface. Containing most of the Earth's breathable air (oxygen and nitrogen), it's a region with warmer temperatures closer to the surface and cooler temperatures farther away which results in the rising and falling air that generates weather.
