The crust and upper mantle of the earth is called the:
lithosphere |
|
atmosphere |
|
geosphere |
|
hydrosphere |
The biosphere is the global ecological system integrating all living beings and their relationships. This includes their interactions with the lithosphere (the rigid outer part of the earth, consisting of the crust and upper mantle), hydrosphere (all surface water), and atmosphere (the envelope of gases surrounding the planet).
Convert -20C° to F°.
-36 |
|
36 |
|
78 |
|
-4 |
To convert from C° to F° use:
\(F° = {9 \over 5}C° + 32\)
\(F° = {9 \over 5}(-20) + 32\)
\(F° = {-180 \over 5} + 32\)
\(F° = -36 + 32 = -4\)
What part of the brain is responsible for the major senses (thinking, hearing, seeing)?
medulla |
|
cerebellum |
|
cerebrum |
|
brainstem |
The cerebrum is the major part of the brain and is responsible for the main senses (thinking, hearing, seeing).
As part of the carbon cycle, plants release carbon into the atmosphere through which process?
evaporation |
|
decomposition |
|
sedimentation |
|
photosynthesis |
The carbon cycle represents the ciruit of carbon through Earth's ecosystem. Carbon dioxide (CO2) in the atmosphere is absorbed by plants through photosynthesis. Plants then die and release carbon back into the atmosphere during decomposition or are eaten by animals who breathe (respiration) the carbon into the atmosphere they exhale and produce waste which also releases carbon as it decays.
The energy posessed by a thrown baseball is an example of what kind of energy?
kinetic |
|
gravitational |
|
transitional |
|
potential |
Kinetic energy is the energy posessed by a moving object. Potential energy is stored energy in a stationary object based on its location, position, shape, or state.
