An air mass forms over the North Pole region describe what you think the temperature and humidity of this air mass will be like?
Answer: hope this helps :)
The motion of air mass motion is usually based upon the air flow in the upper atmosphere. As the jet stream changes intensity and position, it affects the motion and strength of air masses. Where air masses converge, they form boundaries called "fronts".
3-D view of a cold front.
Fronts are identified by change of temperature based upon their motion. With a cold front, a colder air mass is replacing a warmer air mass. A warm front is the opposite affect in that warm air replaces cold air. There is also a stationary front, which, as the name implies, means the boundary between two air masses does not move.
The motion of air masses also affects where a good portion of precipitation occurs. The air of cold air masses is more dense than warmer air masses. Therefore, as these cold air masses move, the dense air undercuts the warmer air masses forcing the warm air up and over the colder air causing it to rise into the atmosphere.
So, fronts just don't appear at the surface of the earth, they have a vertical structure or slope to them as well. Warm fronts typically have a gentle slope so the air rising along
How might evidence from an experiment such as this help shape Darwin’s ideas about evolution?
Explanation:
Darwin, is a brilliance ahead of his time.
He has proven evolution by his observations in the field. EXAMPLE/
He started with plants..a control group & experimental plants he grew himself. After that, he has proven, (evolution theory with environmental variances determines how animals adapt to a new environment)... it is not possible to grow a tropical plant in the midwest without warmth, humidity, water etc...
He had proven through his observations that giraffes have long necks so they can reach the higher branches of food while living in arid climates.
While his counterparts disagreed, he had visited these places worldwide 2 study this.

Do we still have high tides and low tides during neap tides and spring tides? Yes or No?
Answer:Yes
Explanation:
7 days after a spring tide, the sun and moon are at right angles to each other. ... This produces moderate tides known as neap tides, meaning that high tides are a little lower and low tides are a little higher than average. Neap tides occur during the 1st and 3rd quarter moon, when the moon appears "half full.

Explanation:
Complete the sentence. The ________________ of extra rabbits into a forest ecosystem can affect the population of other herbivores already living there.
- birth rate
- death rate
- emigration
- immigration
The immigration of extra rabbits into a forest ecosystem can affect the population of herbivores living in the forest.
What is immigration?Immigration is the movement of people or animals from external locations into a population.
With new individuals moving into a population, the population size increases with other factors being constant.
With the increase in the population size, competition for resources increases accordingly.
Thus if extra rabbits move into a forest ecosystem, the population of herbivores existing in the ecosystem would be affected because competition for food would increase.

Answer:
Controls allow the experimenter to minimize the effects of factors other than the one being tested. It's how we know an experiment is testing the thing it claims to be testing. This goes beyond science — controls are necessary for any sort of experimental testing, no matter the subject area.
Explanation:
Hope it helped <3
The role of control in an experiment is to minimize the effects of factors.
Scientific control is an experiment in which a subject (or a group of subjects) is not tested for a dependent variable (or variables). The addition of control to an experiment is essential for obtaining the results of the empirical data.
A control variable is a variable that is held constant throughout a study. It is not a study variable, but it is controlled because it has the potential to affect the study results.
It is used for comparisons to confirm the results of an experiment. It is used to guarantee that the measured dependent variable is influenced only by the changed independent variable and not any other variables (controls) in the experiment.
