At what approximate depth is the boundary between the mantle and outer core?
At the base of the mantle, about 2,900 kilometers (1,802 miles) below the surface, is the core-mantle boundary, or CMB. This point, called the Gutenberg discontinuity, marks the end of the mantle and the beginning of Earth’s liquid outer core.
What is at the center of the Earth?
At the center of Earth is a solid iron inner core. The hot dense core has a radius of about 759 miles (1,221 kilometers) and a pressure of about 3.6 million atmospheres (atm).
What is the approximate pressure of the outer core?
Earth’s outer core has pressures that range between 135 and 330 Gigapascals (1.3 to 3.3 million atmospheres), and temperatures between 4,000 and 5,000 Kelvin (3,727 to 4,727 degrees Celsius, or 6,740 to 8,540 degrees Fahrenheit.
What is center of Earth line called?
The Equator is an imaginary line around the middle of Earth. It is halfway between the North and South Poles, and divides Earth into the Northern and Southern Hemispheres.
What is the world in the center of the Earth called?
Finally, the center of Earth is called the core. It is an extremely dense area composed mainly of metals, where the temperature is above 6,000 degrees Celsius. Part of this heat, carried by the slow movement of molten matter, rises toward the surface and warms Earth’s crust.
What is the layer called at the center of Earth?
The core is the centre of the earth and is made up of two parts: the liquid outer core and solid inner core. The outer core is made of nickel, iron and molten rock. Temperatures here can reach up to 50,000 C.
What is the approximate value of radius of earth?
The value, symbolized rearth, is equal to approximately 6,371,000 meters (6.371 x 106 m). This is roughly 6,371 kilometers (km) or 3,960 statute miles.
How do you approximate the radius of the earth?
So, for him the following relationship between objects will apply: 7.2 / 360 = 787 / x. Here x is the circumference of the earth. On solving the circumference of the earth we get 39,350 kilometres. r = 39350/ 6.28 = 6267 kilometer.
What is the radius of earth according to class 9?
The radius of the earth is about 6370 km.
What is the approximate distance from the surface to the center of the Earth Brainly?
Answer: the approximate distance from the surface to centre of earth is 3959 miles or 6371 km.
What is the equal distance of a point from the center called?
equidistant Add to list Share. Two objects are equidistant from a point if the distance between each object and that point are the same.
What is the distance from side to side through the center of the Earth called?
Its diameter (the distance from one side to the other through Earth’s center) is 7,926 miles (about 12,756 kilometers). Earth is slightly smaller when measured between the North and South Poles which gives a diameter of 7,907 miles (12,725 kilometers).
What is the approximate distance from the surface to the center of the Earth Mcq?
It is approximately 6,371 km or 3,959 miles.
What is the approximate distance from the surface to the center of the Earth Brainly?

What is the approximate distance from our Solar System to the center of our galaxy?
The Solar System is located at a radius of about 27,000 light-years (8.3 kpc) from the Galactic Center, on the inner edge of the Orion Arm, one of the spiral-shaped concentrations of gas and dust. The stars in the innermost 10,000 light-years form a bulge and one or more bars that radiate from the bulge.
How far from the center of the Earth is the center of mass of the Earth moon system R nothing m?
The center of mass of the earth–moon system is located at a distance 4.6 × 106 m from the center of the earth—one choice for origin—or about 1.8 × 106 m beneath the surface of the earth—a second choice for origin (Figure 10.4).
