To convert from C° to F° use:
\(F° = {9 \over 5}C° + 32\)
\(F° = {9 \over 5}(5) + 32\)
\(F° = {45 \over 5} + 32\)
\(F° = 9 + 32 = 41\)
During continental drift, the drifting plates move across which of the following?
sediment |
|
fault lines |
|
water |
|
liquid mantle |
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.
In taxonomy, domains are the broadest classification of life. How many domains are there?

The broadest classification of life splits all organisms into three groups called domains. The three domains of life are bacteria, archaea and eukaryota.
Which of the following describes the Earth's mantle?
solid |
|
primarily liquid |
|
liquid |
|
primarily solid |
Mantle makes up 84% of the Earth's volume and has an average thickness of approximately 1,800 miles (2,900 km). It is dense, hot, and primarily solid although in places it behaves more like a viscous fluid as the plates of the upper mantle and crust gradually "float" along its circumference.
Which of the following states of matter exists at the highest temperature?
none of these |
|
gas |
|
liquid |
|
solid |
Solids exist at a lower temperature than liquids which exist at a lower temperature than gases.
