Which word is most closely related to the words Earth's interior? A. gas B. liquid C. liquid-like D. solid
i am a tad confused not sure on this one can u help me @MariahDimond ?
plz help anyone!?
@MariahDimond
?
hello?
@Nnesha i need u no one is helping!!!!!!!!!!!
The distance from Earth's surface to its center is about 3,975 miles (6,395 kilometers). Scientists have divided the interior of Earth into various layers, based on their composition. The crust, or outer portion, varies in depth from 5 to 25 miles (8 to 40 kilometers). Below the crust is the mantle, which extends to a depth of about 1,800 miles (2,900 kilometers). Below that is the core, composed of a liquid outer core about 1,380 miles (2,200 kilometers) in depth, and a solid inner core about 780 miles (1,300 kilometers) deep. From direct observation, core samples, and drilling projects, scientists have been able to study the rock layers near the planet's surface. However, this knowledge is limited. The deepest drill hole, just over 9 miles (15 kilometers) in depth, penetrates only about 0.2 percent of the distance to Earth's center. Geologists collect information about Earth's remote interior from several different sources. Some rocks found at Earth's surface originate deep in Earth's crust and mantle. Meteorites that fall to the planet are also believed to be representative of the rocks of Earth's mantle and core. Meteor fragments presumably came from the interior of shattered extraterrestrial bodies within our solar system. It is likely that the composition of the core of our own planet is very similar to the composition of these extraterrestrial travelers. Another source of information, while more indirect, is perhaps more important. That source is seismic, or earthquake, waves. When an earthquake occurs anywhere on Earth, seismic waves travel outward from the earthquake's center. The speed, motion, and direction of seismic waves changes dramatically as they travel though different mediums (areas called transition zones). Scientists make various assumptions about the composition of Earth's layers through careful analysis of seismic data, a method called subsurface detection.

well its b
becase in the interior is solids liquids and the core
ok thank u
your welcome
plus the the first startimg is the top [{crust,liquid,water,rocks(solid),and then iron witch sarounds the core}]
