Answer:
Sample Response: You could use the Pythagorean theorem, since you know the length of the hypotenuse is 9 + 16 = 25 units and the length of one leg is 15 units. To find the value of a, use the relationship that the the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs. You could also use the geometric mean (leg) theorem, which states that the length of the hypotenuse is to the length of an adjacent leg as that adjacent leg length is to the length of its corresponding segment in the hypotenuse. So you could write and solve the proportion 25/a = a/6.
Explanation:
I just did it
From the triangle given, the ways to find a will be the use of a Pythagorean theorem and a geometric mean.
By using the Pythagorean theorem, one will have to add the square of the legs and find the square root. Since the hypotenuse is 9 + 16 = 25 units and the length of one leg is 15 units. Then, in order to find the value of a, one will have to use the Pythagoras theorem.
Also, one can use the geometric mean theorem. Therefore, the values given will be rewritten as 5/a = a/6. Then, the person can solve the equation.

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 soil erosion?The soil fragments are loosened or washed away during this process in valleys, oceans, rivers, streams, or far-off areas. Due to human activities like agriculture and forestry, this has gotten worse.
The process of soil eroding is ongoing and can happen slowly or rapidly. As a result, there is ongoing topsoil loss, ecological harm, soil collapse, etc. The wearing away of the top soil layer is known as soil erosion. It contributes to soil degradation. The dynamic action of erosive factors, such as water, ice (glaciers), snow, air (wind), plants, and animals (including humans), is what causes this natural process. These factors determine the agents that cause erosion, which can be classified as water erosion, glacier erosion, snow erosion, and wind erosion.

How do erosion and deposition work together to create a moraine?
A.Waves cause erosion along coastlines and deposit sand away from the shore.
B.Surface water in rivers causes erosion, carrying sediment that gets deposited near an ocean.
C.Glaciers cause erosion as they melt, carrying sediment that gets deposited in a thick layer.
D.Winds cause erosion by blowing around sand that gets deposited in large piles.
Glaciers are dynamic ice structures that change their size and shape as they grow and melt. Glaciers cause erosion as they melt, carrying sediment that gets deposited in a thick layer.
---------------------------------------
Glaciers have a high capability of soil denudation and erosion. They are capable of transporting many materials of varying sizes y drive them down the hills.
Remember that in the glacier's interior, there are melted ice streams that acquire a high velocity. They can move material from the base of the glacier and produce erosion.
The term moraine refers to the material deposition caused by glaciers. According to the glaciers' dynamics and the material deposited, there can be several types of moraines.
Fontal moraine
Basal moraine
Endoglacier moraine
Lateral moraine
Central moraine
Basically, moraines types depend on how materials get deposited as the glacier melts, or stays stable, or gets closer to another glacier, etcetera.
Materials can get deposited when falling from the surface of the ice in different directions.
Material can sink into the interior of the ice and get deposited from there.
Material can be driven directly along the glacier's base, as internal streams carry them and the glacier melts.
