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.

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.

There are only two chemical elements which are significantly magnetic and reasonably
common and had appropriate densities,_______and______They concluded therefore that the Earth had to have a______made of
and__________
Pls help me out
Answer:
Iron and Nickel
core
Iron and Nickel
Explanation:
Two of the most popular magnetic chemicals in the world are iron and nickel.
We can now match these metals with the description given in the question to check if they perfectly fit in the blanks.
The densities of iron and nickel are 7874kg/m3 and 8900kg/m3 respectively. To put this into perspective, the density of aluminium is only 2700kg/m3. This means that iron and nickel are really dense solid materials. These materials are strong enough to make the core of the earth.
Because these materials are also magnetic and strong, we can say that they are the materials that form the solid core of the earth's structure.

Answer:
erosion by wind and water will help the peaks to become smaller.
If we could travel time and visit the park shown, the changes will be that the reduction of the peaks' heights will be aided by wind and water erosion.
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.
