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

Answers

Answer 1

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.

When traveling, judging the date of
arrival can be difficult for locations
A. close to the Date Line
B. near the Equator
C. near the Prime Meridian
D. during the summer

Answers

Answer:

The date can be hard for judging close to the Date Line.

Explanation:

The world is divided into meridians, which are also used for setting up time zones. The time zones are set up on every 15 degrees of longitude. All of them can be problematic when it comes to time if we travel between time zones. This is due to that if we travel between time zones we lose or gain hours, depending do we travel east or west.

One of these lines is problematic in particular because it is not just the time but also the date that can change by crossing it. That line is the Date Line. This line is located on the opposite side of the Prime Meridian, stretching north to south across the Pacific Ocean. This is the line when each new day starts, so not just the time but the dates start here as well. Basically, by going across this line, not just an hour that can be lost or gained, but a day can be lost or gained as well.

Formal regions are regions that are defined as such based on one or more characteristics that are shared by the inhabitants of the region. In some cases, the boundaries between formal regions are not visible, while in other cases there are geographical features that clearly distinguish them.

North America, the Caribbean, and Latin America are all examples of this type of region. The majority of the population in each of them has characteristics that are common, but also distinguish them from the other regions. These shared characteristics can be seen in the dominant culture (English-based, Spanish/Portuguese-based, a mixture of several), religion, lifestyle, race, ethnicity, language, etc.

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.

what seafloor structures you would encounter if you could walk underwater from the United States to Europe

Answers

Answer:

The seafloor structures that will be encountered are shelf, slope, rise, abyssal plain, seamounts, and mid-ocean ridge/rift valley.

Explanation:

The Atlantic Ocean is the second-largest ocean in the world. It is divided into two subdivisions, the North Atlantic Ocean and South Atlantic Ocean. The North Atlantic subdivision is the one located between North America on one side, and Europe and Northern Africa on the other side.

If we were to walk from North America to Europe on the ocean floor, then the first structure we will encounter will the relatively wide continental shelf. Next will come to the slope and rise where the seafloor sharply becomes much deeper. Once we reach the bottom of the ocean we will encounter the abyssal plain, and in the abyssal plain, there are also seamounts sharply rising above the seafloor. In the central part of the ocean, we will encounter the mid-ocean ridge, which is where the rift valley is located. After that, we will encounter the same structures that we already encountered just in a reverse manner, with abyssal plain and seamounts coming first, then sharp elevation as we come to the rise and slope, and a relatively small continental shelf.

If you walked underwater from US to Europe, the seafloor structures that you would encounter are:

What is the biggest obstacle to traveling by boat on the Congo River?

D.

Answers

The biggest obstacle to traveling by boat on the Congo River is A. the many cataracts

The numerous cascades on the Congo River are the main challenge for boat passage. Navigation on the Congo River is challenging and dangerous due to a number of strong cataracts, or rapids and waterfalls. The hills and troughs in the riverbed that force the water to flow quickly across them are what generate these waterfalls.

On the Congo River, there are a total of seven major cataracts that make navigation extremely difficult and demand that boats be unloaded and portaged around. There are also shallow places brought on by the drought. Because of the ideal growing conditions provided by these shallow locations, the water plants flourished, producing troublesome obstructions for the boat.

Answer, D look at oceans as highways

Answers

Answer:

D). Look at oceans as highways

Explanation:

Ocean-centered geography lays emphasis on 'viewing the oceans in the form of highways.' This concept allows geographers to ascertain the water paths connecting two or more countries. It views the oceans as highways as it offers a greater context to study the association between the continents more similarly like cities in the highways(oceans) of the world.

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:

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.
