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.
Well, darling, that molten rock beneath the Earth's surface is called magma. It's like the fiery heart of our planet, just waiting to burst out in a volcanic eruption. So, watch out for those lava flows, honey!
Magma and lava are like each other but magma is below the Earth and lava reaches the Earth's surface.
A non-example of magma would be any solid rock found on the Earth's surface or within the Earth's crust. Magma is molten rock located beneath the Earth's surface, whereas solid rocks like granite, basalt, or sandstone are not examples of magma. Additionally, substances such as water, air, or metals are also not examples of magma, as they do not have the same chemical composition or physical properties as molten rock.
Earthquakes take place in the Earth's tectonic plates, which are not thick enough to have earthquakes deeper than 20 km. Below the plates is the magma of the Earth's mantle, and being liquid, the magma does not experience quakes, just currents.
Magma is underground, when it reaches the surface it becomes lava. So solidified magma is really lava. The lava flow is the liquid lava as it goes down the mountain, when hard its just hardened lava.

Magma is just lava inside the earth, and lava is just magma outside the earth.
The mantle.

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.
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.
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.
Magma and lava are like each other but magma is below the Earth and lava reaches the Earth's surface.
Magma is the hot semi-fluid material (lava) that emerges from volcanoes, and is just below the crust, being part of the mantle.
contains hot molten rocks or magma
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.
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
No, astronomers study space. Just remember that the prefix: astro-means space. Geologists study the earth, including tectonic plates.
