Answer:
on Earth, the main differences in air pressure are caused by differences in temperature. Cool air produces high air pressure and warm air produces low air pressure. Warm air wants to rise. When warm air rises, cool air will move in and replace the warm air, causing wind.

How do supranational organizations challenge state sovereignty?
Answer:
Supranational organizations tend to try and put their own rules and laws which the country members have to implement, which in turn means that they are becoming limited in their decision-making on a state level.
Explanation:
There are several supranational organizations in the world, and some of them are the European Union, African Union, and NATO. Even though they are all different and have their own unique characterisitcs, one thing that tends to be a common trait is that they all have their own governmental structure that tends to impose itself over the state governments.
These organizations are very lucrative and attractive for a lot of countries, but the governmental structure of these organizations also makes every member sign a lot of documents that make them obligated to respect and implement the decisions. This basically means that the country members are giving up on part of their sovereignty, and this can be best seen in the EU, where there has been a lot of problems because of it and there is an evergrowing backlash against it.
Which event was a major source of atmospheric oxygen?
photosynthesis
volcanic eruptions
decomposition of water
outgassing
Answer:
Photosynthesis was a major source of atmospheric oxygen.
Explanation:
Earth's atmosphere was not the same as it is in the past. For a larger portion of Earth's history, the atmosphere actually didn't have an atmosphere or the one it had was not suitable for complex lifeforms to develop. This all changed because of one major event, the process of photosynthesis.
Initially, it was the cyanobacteria that started to use this process in order to produce their own food and energy. Basically, this process meant that the cyanobacteria, and a lot of later organisms, were taking in carbon dioxide, use it for their own needs, and release the oxygen. The oxygen was released into the ocean and into the atmosphere, which resulted in a gradual change in the composition of the atmosphere to a degree where it was suitable for larger organisms to start to develop.
What is the thermocline?
beneath 200 meters, ocean water cools at a constant rate of 1°C per 100 meters depth
the ocean area near the polar regions where water temperatures cool
where magma is forced up through the ocean floor along mid-ocean ridges
the area off the continental shelf that declines to the ocean floor
Answer:
Beneath 200 meters, ocean water cools at a constant rate of 1°C per 100 meters depth.
Explanation:
The thermocline is one of the three ocean zones when it comes to separating the ocean waters by temperature and weather waters mix or not. The top layer of water, or the surface water, is called the epilimnion. The second layer, or thermocline, is called metalimnion at starts from 200 meters of depth. And the last one, or deep ocean, is the hypolimnion, starting from 1,000 meters of depth.
The surface layer is the one where the water is the warmest and it mixes. In the second layer, we have the thermocline, where the water is not mixing anymore and it sharply drops in temperature. The water temperature generally drops by 1 degree Celsius per 100 meters of depth. The third layer is the coldest, but there aren't big changes in temperatures between the starting and endpoint of it.

Which of the following is NOT a reason why birth and death rates are high in developing countries?
No birth Control
Religious restrictions
Economic factors
easy access to medical care
Answer:
Easy access to medical care is not a reason for high birth and death rates in developing countries.
Explanation:
A big portion of the developing countries tends to have high birthrates and high death rates. The reason for this are numerous, ranging from political, religious, traditional, economic, low education levels, women being discriminated against, etc. In general, it seems that the lower the status of women is in a society, the higher the birthrates are, and all of the factors that contribute to it actually result in a shorter life span for the whole population.
One thing that doesn't contribute to this is easy access to medical care. Easy access to medical care is not something that is found in a developing country, on contrary, the access to medical care is hard, limited, and for many people out of reach. When medical care is not available for the population the results are always devastating, with high death rates among infants, during birth (both mothers and children), diseases spread very easily and have a much bigger impact, and because of lack of it also the population leaves shorter lives.
What is the thermocline?
beneath 200 meters, ocean water cools at a constant rate of 1°C per 100 meters depth
the ocean area near the polar regions where water temperatures cool
where magma is forced up through the ocean floor along mid-ocean ridges
the area off the continental shelf that declines to the ocean floor
Answer:
Beneath 200 meters, ocean waters cools at a constant rate of 1°C per 100 meters depth.
Explanation:
The ocean water is with the same characteristics throughout all of the oceans. The differences come in differences in temperature, density, salinity, etc. When it comes to temperature, it is what influences the other characteristics, and it is what causes the movement of water in the oceans.
The movement of ocean water occurs because in some parts, the ocean water gets cold, while in others it gets warm. The cold water drops deeper and moves toward the less dense warmer water, and as it gradually warms up itself it rises, pushing the warm water in opposite direction. The water is mixing at the surface, but this is not the case below 200 meters of depth, where water mixing stops. This zone, where the water is not mixing, is known as the thermocline and exists as such throughout all of the oceans.

Be able to describe and explain the formation of a meander and oxbow lake?
Answer:
Geology. An oxbow lake forms when a river creates a meander, due to the river's eroding bank. After a long period of time, the meander becomes very curved, and eventually the neck of the meander becomes narrower and the river cuts through the neck, cutting off the meander and forming an oxbow lake.
Explanation:
An oxbow lake starts out as a curve, or meander, in a river. A lake forms as the river finds a different, shorter, course. The meander becomes an oxbow lake along the side of the river. Oxbow lakes usually form in flat, low-lying plains close to where the river empties into another body of water.

Write a general statement that could be used to determine if other mass extinctions have occurred in Earth’s history. Explain why your statement would is appropriate. 2-3 Sentences.
Answer:
Explanation:
The most appropriate example is the extinction of the dinosaurs. All sorts of theories were put forth. Most think there was a dramatic change in the environment, a change that left no time for the dinosaurs to adapt to that change.
Whatever happened, an asteroid, volcanic eruptions, or something else, whatever you propose has to explain why birds and mammals survived.
So whatever occurred, it had to be dangerous to land animals, but not those who flew or those who could think well enough to avoid whatever was happening around them.
That said, I would propose that it was a virus that was not air born and the genetic make up of mammals could avoid the harmful effects of the virus.
I would propose that this is the only explanation that works. Perhaps the makeup of the blood could not adapt to the extinction. The blood of a dinosaur might not have included very powerful neutrophils (which fight disease).

what is the greenhouse effect in 3 sentences simple terms? do not copy from the internet.
Answer:
Explanation:
Ok
Answer:
What is the greenhouse effect?
The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without this atmosphere.Light energy emitted by the sun warms the earth's surface, which reflects the energy as heat that warms the atmosphere. Much of the heat is captured by greenhouse gas molecules such as water, carbon dioxide, and methane.Radiatively active gases (i.e., greenhouse gases) in a planet's atmosphere radiate energy in all directions. Part of this radiation is directed towards the surface, thus warming it. The intensity of downward radiation – that is, the strength of the greenhouse effect – depends on the amount of greenhouse gases that the atmosphere contains. The temperature rises until the intensity of upward radiation from the surface, thus cooling it, balances the downward flow of energy.A square piece of plywood has side 8cm. A parallelogram with base 6cm and height 5cm is cut from the piece. Find the area of the remaining piece.
Given
A square piece of plywood has side 8 cm.
A parallelogram with base 6 cm and height 5 cm is cut from the piece.
To find
The area of the remaining piece.
Solution
Given that,
Side of square = 8cm.
We know,
Area of square = (side)^2
Area = 8A8
< / p ><p> Aea 64cm^2
Also,
Area of parallelogram :
Area = baseAheight
Given that,
base = 6cm & height =5cm.
Area = 6A5
< / p>< p ? 30cm^2
Now,
Remaining area = area of square - area of parallelogram
64 - 30
< / p ><p> 34 cm^2
Remaining Area = 34cm^2

Explanation:
The fastest flow is on the inside of a meander bend. True or false
Answer:
True.
Explanation:
Because when the water flows faster it has more power to erode the outside bank. The outside bend of the meander becomes deeper, reducing friction and allowing for even faster flow of water, which in turn means more erosion. On the inside bend of the meander the river is flowing much slower.

What happens at a divergent boundary?
A. Two tectonic plates slide past each other.
B. One tectonic plate slides under another.
C. Two tectonic plates move away from each other.
D. Two tectonic plates move toward each other.
Two tectonic plates move away from each other at a divergent boundary. Thus, option C is correct.
What is the tectonic plates?A tectonic plate is also known as a lithospheric plate, is a substantial slab of solid rock with an uneven shape that is typically made up of both continental and oceanic lithosphere.
The Pacific and Antarctic Plates are among the largest plates, but they can range in size from a few hundred to thousands of kilometres broad. People can't survive underwater, therefore it created the continents on which we now reside.
Volcanoes are produced when plates clash and subduct (when one plate slides under another). Peoples believe that this procedure, repeated numerous times, is what created the continents.
Therefore, option C is correct, that the At a diverging border, two tectonic plates advance apart.
