[13:3] He is the One who constructed the earth and placed on it mountains and rivers. And from the different kinds of fruits, He made them into pairs - males and females. The night overtakes the day. These are solid proofs for people who think.
 
[88:17] Why do they not reflect on the camels and how they are created? [88:18] And the sky and how it is raised. [88:19] And the mountains and how they are constructed. [88:20] And the earth and how it is built.
The distance to the center of the Earth is 6,371 kilometers (3,958 mi),
Earth's inner core is the innermost geologic layer of the Earth. It is primarily a solid ball with a radius of about 1,220 kilometres (760 miles), which is about 20% of the Earth's radius. We have no samples of the Earth's core available for direct measurement, but from analysis of seismic waves and the magnetic field the inner core is believed to be composed of an iron–nickel alloy with some other elements. The temperature at the inner core's surface is estimated to be approximately 5700 K (5430 °C or 9806 °F), which is about the temperature at the surface of the Sun.
Earth's outer core is a fluid layer about 2,400 km (1,500 mi or 40% of Earth’s radius) thick and composed of mostly liquid iron and nickel. Its outer boundary lies 2,890 km (1,800 mi) beneath Earth's surface. The transition between the inner core and outer core is located approximately 5,150 km (3,200 mi) beneath the Earth's surface.
Earth’s mantle: The mantle is the mostly-solid bulk of Earth's interior. The mantle lies between Earth's dense, super-heated core and its thin outer layer, the crust. The mantle is about 2,900 kilometers (1,802 miles 40% of Earth’s radius) thick, and makes up a whopping 84% of Earth's total volume.
Humans have drilled over 12 kilometers (7.67 miles) in the Sakhalin-I. In terms of depth below the surface, the Kola Superdeep Borehole SG-3 retains the world record at 12,262 metres (40,230 ft) in 1989 and still is the deepest artificial point on Earth.
The Earth's crust is a thin shell on the outside of the Earth, accounting for less than 1% of Earth's volume. The Earth's crust ranges from 5–70 kilometres (3.1–43.5 mi) in depth. Because Earth’s crust are less dense than the mantle below, both types of crust "float" on the mantle.
Mountains Moving
Continental drift
The Earth has 7 major plates. Each of these plates float onto of the Earth’s mantle. Each year each plate moves about an inch. When these plates collide into one another the plate that is stronger moves below and the plate that is weaker moves on top. Then over millions of years this accumulation in moving causes the formation of mountains.
Mountains are waves of stone - their time horizon is much longer and move much slower
[27:88] When you look at the mountains, you think that they are standing still. But they are moving, like the clouds. Such is the manufacture of GOD, who perfected everything. He is fully Cognizant of everything you do.
 
[79:30] He made the earth egg-shaped.

The root for the word has predominately two meanings: the first meaning is of an egg, but specifically an ostrich egg.
The word دَحَاهَا / dahaha in Arabic comes from the word for an egg, but specifically an ostrich egg. The Earth is not a perfect sphere it is an Oblate Spheroid, where the north and south pole are slightly compressed and the equator is slightly expanded.
What kind of an ostrich did the Arabs at the time of the revelation of the Quran have among
