The core of the earth is a hot, compact ball made primarily of iron. There are roughly 1,220 kilometers around it (758 miles).
The Earth's core is our planet's tremendously hot and dense interior. The ball-shaped core lies beneath the cold, brittle crust and the mainly solid mantle. The core is located around 2,900 kilometers (1,802 miles) below the Earth's surface and has a radius of roughly 3,485 kilometers (2,165 miles). The Earth is older than the core. Around 4.5 billion years ago, when Earth was originally forming, it was a uniform ball of hot rock.
The ball heated up even more due to radioactive decay and heat left over after planetary formation (the collision, accretion, and compression of space rocks). After roughly 500 million years, our young planet's temperature reached 1,538° Celsius (2,800° Fahrenheit), the temperature at which iron melts.

What happened after the 1986 Chernobyl nuclear disaster?To lessen radioactive contamination at and around the facility, the Soviet government destroyed and buried nearly a square mile of pine forest close to the plant. The last reactor at Chernobyl shut down in December 2000 after three others were restarted and eventually shut down permanently.
In response, the International Chernobyl Project was established by the IAEA, which conducted a visit to the damaged areas and produced a thorough report on radioactive effects and safety precautions. Standards for nuclear safety were raised, and hazardous plants were shut down.

famous archaeological site in jordan crossword clue
The well-known archaeological site Petra is located in the desert in southwest Jordan.
In the southwest of Jordan, in the Wadi Mousa, or Valley of Moses, are the beautiful remains of ancient Petra. Petra, the former seat of the Edomite Kingdom, was taken by Nabataean invaders in 300 BC, solidifying their control of the area. It served as the Nabatean Kingdom's capital. It is referred known as the "Rose City" because of the tombs and temples that are carved into the pink sandstone cliffs that may be reached via a small canyon called Al Siq. The 45-meter-tall Al Khazneh, also known as The Treasury and with an elaborate Greek-style exterior, is arguably the most well-known building there.

What is Earth's average angular speed?.
Earth's average angular speed is the speed at which it rotates around its own axis, measured in degrees per unit of time.
The Earth completes one full rotation on its axis in 24 hours or 86,400 seconds. The Earth's angular speed is measured in degrees per second (°/s), and to find the average angular speed, we need to find the number of degrees the Earth rotates through in one day and divide it by the number of seconds in one day.
The Earth rotates through 360 degrees in one day, so the average angular speed is: Angular speed = (360 degrees) / (86,400 seconds) = 0.00416667 degrees/second
To convert it to radians per second:
Angular speed = (360 degrees) * (π/180) / (86,400 seconds) = 7.2921158 x 10^-5 radians/second
Note that this is the average angular speed of Earth, which is the same for any point on the surface of Earth, but the actual angular speed at any point on the surface of Earth varies slightly due to the effects of the Earth's oblateness and rotation around the sun.

Which i the correct layer of rock equence in order from OLDEST to YOUNGEST? edpuzzle
Based on the law of superposition, the correct layer of rock sequence in order from oldest to youngest is E, B, C, D, A. (Option B)
The law of superposition is a major principle of stratigraphy which states that within a sequence of layers of sedimentary rock, the oldest layer is located at the base and the layers are progressively younger with ascending order in the sequence. Scientists use this principle to determine the relative ages of rock strata, or layers. Hence, the layers are superimposed on top of another. The youngest layer is located at the top. Based on this, layer E is oldest which followed by B and C. The younger layers are D and A.
Note: The question is incomplete. The complete question probably is: Which is the correct layer of rock sequence in order from oldest to youngest? A) A, B, C, D, E B) E, B, C, D, A C) E, D, C, B, A D) C, B, A, D, E

A Divide is the high point or ridge that determines the direction rivers flow.
A divide is a high point or ridge that divides two drainage basins. It is typically formed by geographic features such as mountains, hills, or plateaus, and it determines the direction in which rivers flow.
A divide acts as a barrier for water, with upstream and downstream sections of the same river being separated by the divide.
This barrier prevents water from flowing from one drainage basin to another, and instead determines the direction in which the water will flow.

german scientist that developed theory of continental drift
The theory of continental drift, which holds that Earth's continents move, was put forth by German scientist Alfred Wegener.
The scientist Alfred Wegener is most closely connected with the concept of continental drift. Wegener wrote a paper outlining his notion that the continents were "drifting" across the Earth, occasionally crashing through oceans and into one another, in the early 20th century. He referred to it as continental drift.
Between 1912 and 1929, he published a substantial amount of convincing fossil and geological evidence in support of his theory, but most other scientists disregarded it. The concept of continental drift didn't enter the mainstream of science until the 1960s.

how have the countries of central asia been governed over the centuries?
The past of the many peoples who have inhabited Essential Asia is central to our understanding of the region. Such people's lifestyle is mostly influenced by the terrain and climate of the region.
Agriculture in the area is challenging due to the area's aridity, and its isolation from the sea prevents significant trade. As a result, the area saw the development of few large cities. For thousands of years, the region was ruled by horse-riding steppe nomads.
Conflict characterized the interactions between the steppe nomads and the established inhabitants of Central Asia. The nomadic way of life was perfectly suited to combat, and because of the deadly tactics and prowess of their horse archers, the steppe horse riders became some of the most militarily powerful people in the world. Occasionally, tribal leaders or shifting circumstances would lead to the organization of multiple tribes into a single military force, which would then frequently launch conquest expeditions, especially into more "civilized" areas.

Which is not a major cause of the erosion of the mountains?.
The Appalachian Mountains are being eroded for reasons other than coal extraction.
One of the oldest mountain ranges in the world is the Appalachian Mountains. They were one of the world's tallest mountains in their prime and developed more than 300 million years ago. But as we can now see, these mountains are not even close to being the tallest; instead, depending on which part of them, they range in height from medium to low.
The erosion is what caused these mountains to lose a significant amount of height. It has been damaged by erosion continuously for 300 million years, which has resulted in the gradual loss of rock strata, flattening, and development of gentle slopes. The erosion of the Appalachians has been influenced by rain, water runoff, wind, high and low temperatures, ice, and other environmental factors.

which boundary is associated with the building of the himalaya mountains?
Mountain ranges are produced when two continental plates collide. This kind of convergent plate boundary produced the magnificent Himalaya Mountains.
When two continental plates meet, it forms a convergent plate boundary. The continental lithosphere is quite thick and has a low density. The lithosphere of a continent cannot subduct. Therefore, when two continental plates meet, they simply crash into one another. Similar to what happens when you place your hands on opposite sides of a piece of paper and pull them together, this also occurs. The only direction the material can go is up (see figure below)! Earthquakes and metamorphic rocks are produced as a result of the collision's extremely strong forces. But magma cannot penetrate the crust because it is too thick.
