Answers
Answer:
no they don't inside earth but robots go and satellite helps
Answer:
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.
The iron isn't pure—scientists believe it contains sulfur and nickel, plus smaller amounts of other elements. Estimates of its temperature vary, but it is probably somewhere between 9,000 and 13,000 degrees Fahrenheit (5,000 and 7,000 degrees Celsius).
Explanation:
how do scientists know:
Scientists have been able to distinguish the layers of the Earth that are made of different materials that transmit waves at different speeds. Based on these seismic observations, the Earth's interior has been divided into the following layers: Crust: A very thin, solid outer layer.
