4.) How do scientists know dark energy exists?

5.)What observations and reasoning led to the development of Hubble's Law?

6.) What was the foundation of Georges Lema^itre's Big Bang Theory?​

Answers

Answer 1

Answer:

Not too sure on 3,5, and 6, but here's the other three.

1. The three types of star clusters differ in size and location. Globular clusters are the largest, and are located in a halo around a galaxy. Open clusters are the second largest, only containing hundreds of stars rather than the hundreds of thousands in globular clusters. They're found in the plane of the galaxy. The smallest are associations, which contain extremely young stars and can be found in gas and dust regions of the galaxy.

2. Dwarf galaxies lack evidence of recent star formation, contain little to no gas, and are elliptical.

4. We can't observe dark energy, however, we can observe its effect on other observable things. For instance, there is a galaxy that when we observe it, we see it five times. As in, it appears that we are seeing five different galaxies, but it's just the one. This happens because the light being produced from the galaxy is warped by immense gravity.

How do supranational organizations challenge state sovereignty?

Answers

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.

Pls help me out

Answers

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.

Which major mountains are found In the valley & ridge region?

Answers

is a U-valley formed by movement in glaciers. A glacier or U-shaped valley has a wide flat floor and steep sides.
Glaciers are a thick mass of moving ice. V-shaped valleys become U-shaped valleys as glaciers move through them. First it is a typical river valley and then water flows into the cracks, which over time cuts a deeper V-shape. Glaciers then fill the valley, widen it and stretch the canal, which when the glacier melts leaves a U-shaped valley. Gravity causes the glacier to slide down. Then it pulls rocks, sand and gravel, ie sediment

. These wear down into the rock and form a U-valley. The differences between a V-valley and a U-valley are that a glacier works downwards and outwards while the V-valley then works its way down the glacier. and deepen the valley and change it to a U-shape.

u-shaped valley was formed by ice formation. U-shaped valleys are mostly found near the rocky mountain.
Glaciers pass through jagged mountain valleys making them smooth and u-shaped after the ice retreats.
The ice scrapes the sides and bottom

valleys are low land areas between hills or mountains. they usually have rivers that run through the middle

When a glacier pushes itself forward in a mountain landscape, the ice grinds not only on the surface but also on the sides of the valley and in this way characteristic U-valleys are formed

the valley is formed by erosion, or gradual wear of elements, such as water or wind. valleys can also be formed by movements in the earth's crust or gracias. the graciers drop depressions into the earth's surface
valleys are helpful to people because they are usually close to the river. the flowing stream provides access to food and potable water. they also give people exotic plants and animals to eat or harvest



In what type of landscape can you most often find this landform?
You can find U-dal in mountain areas everywhere in, for example, Sweden, Himalayas

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.

Answers

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.

Which event was a major source of atmospheric oxygen?

photosynthesis

volcanic eruptions

decomposition of water

outgassing

Answers

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.
