An asteroid belt holds many of the asteroids in our solar system. It is located between the orbits of which planets?
Mars and Jupiter |
|
Mercury and Venus |
|
Jupiter and Saturn |
|
Mars and Earth |
The solar system also contains over a million rocky fragments of at least 1km in diameter called asteroids as well as millions more with smaller diameters. Many of these asteroids are an asteroid belt between the orbits of Mars and Jupiter.
50°F is how many °C?
10 |
|
58 |
|
122 |
|
-10 |
The formula to convert from F° to C° is:
\(C° = {5 \over 9} (F° - 32)\)
plugging in our values gives:
\(C° = {5 \over 9} (50 - 32)\)
\(C° = {5 \over 9} (18)\)
\(C° = {90 \over 9}\)
\(C° = 10\)
What is a major difference between the somatic and autonomic nervous systems?
one controls thinking, the other controls feeling |
|
one controls voluntary activity, one controls involuntary activity |
|
one is inherited, the other is learned |
|
each belongs to a different nervous system |
Both are part of the peripheral nervous system. The somatic nervous system sends sensory information to the central nervous system and controls voluntary actions while the autonomic nervous system regulates involuntary activity in the heart, stomach, and intestines.
During continental drift, the drifting plates move across which of the following?
fault lines |
|
sediment |
|
liquid mantle |
|
water |
The crust and the rigid lithosphere (upper mantle) is made up of approximately thirty separate plates. These plates more very slowly on the slightly more liquid mantle (asthenosphere) beneath them. This movement has resulted in continental drift which is the gradual movement of land masses across Earth's surface. Continental drift is a very slow process, occurring over hundreds of millions of years.
An element in the physical state of __________ maintains a constant volume but their shape depends upon the shape of their container.
liquid |
|
gas |
|
solid |
|
plasma |
In the liquid state, molecules flow freely around each other and exist at a higher temperature range than the same substance in a solid state. Liquids maintain a constant volume but their shape depends upon the shape of their container.
