When the clouds become too saturated with water, the water is released as precipitation in the form of:
ice |
|
snow |
|
rain |
|
snow or ice |
Rising into the atmosphere, the water condenses into clouds. When the clouds become too saturated with water, the water is released as snow or ice precipitation which may warm as it falls to reach Earth as rain.
In taxonomy, domains are the broadest classification of life. How many domains are there?
3 |
|
dozens |

6 |
|
5 |
The broadest classification of life splits all organisms into three groups called domains. The three domains of life are bacteria, archaea and eukaryota.
Cirrus clouds generally occur in what kind of weather?
stormy |
|
fair |
|
hot |
|
freezing |
Cirrus clouds are thin, wispy high-altitude clouds composed of ice crystals that originate from the freezing of supercooled water droplets. Cirrus clouds generally occur in fair weather and point in the direction of air movement at their elevation.
Which of Earth's layers has weather?
stratosphere |
|
mesosphere |
|
thermosphere |
|
troposphere |
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.
Elements in the same group in the Periodic Table of the Elements have the same:
number of electrons in their outer electron shell |
|
number of electrons |
|
number of atomic mass units |
|
number of electron shells |
The columns of the Periodic Table are called groups and all elements in a group have the same number of electrons in their outer electron shell. The group that an element occupies generally determines its chemical properties as the number of outer shell electrons establishes the way it reacts with other elements to form molecules. So, because each element has the same number of electrons in its outer shell, each has similar reactivity.
