How do geologists know that the earth is not just filled with magma?

Seismic waves react differently when passing through fluids and different densities of solid material. Seismic wave interpretations reveal that only the outer core is essentially a liquid.

Is lava and magma the same?
Magma and lava are like each other but magma is below the Earth and lava reaches the Earth's surface.
Why arent fossils found in extrusions and intrusions?
Because extrusion and intrusions are melted magma that hasn't reached the earth's surface and the hot magma can't just pick up fossils that are already in place.
Why is lava and magma not a rock?
Lava and magma are not rocks because they are liquids and cant harden because they are to hot to harden and cant cool themselves down long enough to form a hard structure. Magma and lava is rock - it's just been superheated by the Earth's core.
What happens after a metamorphic rock is formed?
Metamorphic rock does not come out of magma. Igneous rock does.
What mars look like inside?
Mars has a magma core with millions and millions of layers of rocks and sediments, just like what Earth has.
Why lava and magma is together?
Magma is just lava inside the earth, and lava is just magma outside the earth.
What of the earth is made up of magma and is found just beneath the earth's crust?
The mantle.
Do geologist just study the earth?
Not necessarily; it depends on your focus and your definition of Earth. Some geologists study glaciers and climate patterns from the past, which may not be what you define as "Earth". There are also planetary geologists, who study Earth-like processes on other planets and other extra-terrestrial bodies.
Information on geologist?
What is a geologist? A geologist is a person who studies the Earth and the materials it's made up of (A.K.A. geology). Geologists are also the subject of this speech. There are many kinds of geologists like economic geologists and marine geologists are two examples but I'm just going to deal on the general geologist. A major science they use is Earth science. Earth Science is any of the basic geologic sciences that are connected with the source, arrangement, and physical phenomena of the earth. Using this science geologists can identify countless things. They also identify rocks & minerals. To help identify a mineral's hardness, geologists use Moh's Mineral Scale of Hardness. This scale lists 1-10 weakest to hardest minerals. Moh's Scale is very helpful to geologists. There is also a lot of math involved with geology. One of these is calculus. Calculus is analysis of numbers with special symbols. Calculus helps with making graphs, diagrams, 3-D and 2-D maps, etc. Plus, using calculus geologists can make mathematical models to find oil. Most geologists need to use calculus! SO CALCULUS IS VERY VERY important to Earth Science. Like I said before, geologists are very good at studying rocks. There are three types of rocks: Igneous which is formed by magma and/or lava, Sedimentary which is formed by tiny & big sediments and Metamorphic which is a rock changed by heat & pressure. An example of Igneous is Basalt, a sedimentary is shale and a metamorphic is quartzite. Guess who figured this out. GEOLOGISTS! If it weren't for geologists, we really wouldn't know what rocks were, are, and will be.
Is magma a gas?
No, magma is just molten rock that lies under the Earth's Crust (when outside of the Crust it is lava). What you are thinking of is probably plasma, which can be formed by superheating gas.
Are magma form on the earth surface or in the interior?
Magma is the hot semi-fluid material (lava) that emerges from volcanoes, and is just below the crust, being part of the mantle.
Asthenosphere?
contains hot molten rocks or magma
Is lava and magma the same?
Magma and lava are like each other but magma is below the Earth and lava reaches the Earth's surface.
Which of these scientists would be interested in the earth layers?
They want to look into further details about any natural disaster that might happen that can damage the earth or OR they just want to discover more about the Earth's layers
Why arent fossils found in extrusions and intrusions?
Because extrusion and intrusions are melted magma that hasn't reached the earth's surface and the hot magma can't just pick up fossils that are already in place.
Is Mars filled with gravity?
Filled with gravity? It does have gravity, just not as great as Earth's since it is smaller. The greater an object, the more gravity it has to pull objects close to it.
What liquid is below the surface of the earth?
The liquid below the surface of the earth is mostly molten rock, called magma. It is found in the mantle layer of the earth, between the crust and the core. The outer core of the earth is also a liquid, consisting mainly of molten iron and nickel.
