What part of the brain is responsible for for balance, movement, and muscle coordination?
cerebellum |
|
brainstem |
|
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.
-40°F is how many °C?
\({40 \over 9}\) |
|
-40 |
|
-8 |
|
\(-{40 \over 9}\) |
The formula to convert from F° to C° is:
\(C° = {5 \over 9} (F° - 32)\)
plugging in our values gives:
\(C° = {5 \over 9} (-40 - 32)\)
\(C° = {5 \over 9} (-72) = {{-72 \times 5} \over 9}\)
\(C° = {-360 \over 9}\)
\(C° = -40\)
The crust and lithosphere of the Earth is made up of which of the following?
plates |
|
sedimentary rock |
|
metamorphic rock |
|
continents |
The crust and the rigid lithosphere (upper mantle) is made up 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.
When two air masses meet and neither is displaced, what kind of front is present?
stationary |
|
occluded |
|
cold |
|
warm |
When two air masses meet and neither is displaced, a stationary front is created. Stationary fronts often cause persistent cloudy wet weather.
