What are the main features of oceanic crust?
Not including a sedimentary cover of variable thickness and composition, the oceanic crust consists of three layers: (1) a relatively thin uppermost volcanic layer of basaltic lavas known as mid-ocean ridge basalts (MORB) erupted on the seafloor; (2) a thicker layer of more coarsely crystalline, intrusive basaltic …
What is the crust made of?
The crust is made of solid rocks and minerals. Beneath the crust is the mantle, which is also mostly solid rocks and minerals, but punctuated by malleable areas of semi-solid magma. At the center of the Earth is a hot, dense metal core.

Can you dig a hole to China?
Take a closer look at a globe: China is actually not antipodal to the United States. That would be impossible, since they’re both in the Northern Hemisphere. If you dug a hole from anywhere in the lower 48 states straight through the center of the Earth, you’d actually come out… in the middle of the Indian Ocean.
Can we go to Earth’s core?
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.
Where will I end up if I dig a hole?
Earth is a sphere, so if you start digging in the Northern Hemisphere, then you’ve got to end up in the Southern Hemisphere. China is far away, but it’s also in the Northern Hemisphere. So if you’re digging from America, then China can be ruled out from the get-go.

What does inside of Earth look like?
The Earth’s interior is composed of four layers, three solid and one liquid—not magma but molten metal, nearly as hot as the surface of the sun. The deepest layer is a solid iron ball, about 1,500 miles (2,400 kilometers) in diameter. Although this inner core is white hot, the pressure is so high the iron cannot melt.
