In the classification of life, which of the following is not a domain?
animalia |
|
eukaryota |
|
archaea |
|
bacteria |
The broadest classification of life splits all organisms into three groups called domains. The three domains of life are bacteria, archaea and eukaryota.
Which is the proper order of Earth's atmospheric layers from the surface up to space?
thermosphere, mesosphere, stratosphere, troposphere |
|
troposphere, stratosphere, mesosphere, thermosphere |
|
mesosphere, thermosphere, stratosphere, troposphere |
|
stratosphere, troposphere, mesosphere, thermosphere |
The troposphere is the closest layer to Earth, followed by the stratosphere, mesosphere, and finally the thermosphere which borders space.
Large, puffy, mid-altitude clouds with a flat base and a rounded top describe which of the following?
fog |
|
stratus clouds |
|
cumulus clouds |
|
cirrus clouds |
Cumulus clouds are large, puffy, mid-altitude clouds with a flat base and a rounded top. These clouds grow upward and can develop into a cumulonimbus or thunderstorm cloud.
When light travels between two substances it bends. This is called:
refraction |
|
conduction |
|
reflection |
|
convection |
Because different materials have different refractive indices, light changes speed when passing from one material to another. This causes the light to bend (refraction) at an angle that depends on the change in refractive index between the materials. The greater the difference, the higher the angle of refraction.
In the water cycle, infiltration is most closely related to:
rivers |
|
oceans |
|
runoff |
|
water table |
The water then accumulates as runoff and eventually returns to bodies of water or is absorbed into the Earth (infiltration) and becomes part of the water table, an underground resevoir of fresh water.
