What are the methods to know the interior of the earth?
Geologists have discovered a lot about the interior composition of the Earth by studying 'S' and 'P' seismic waves. For example, they learned that Earth has a liquid outer core when they noticed that 'S' waves didn't come out on the other side of Earth because they are unable to travel through liquids.
What happens when s waves hit the outer core of earth?
Because the Earth's core is liquid; S-waves can't travel through liquid.
What happens to seismic waves when they pass through the liquid outer core?
There are two types of waves. There are S waves (sheer waves) and P waves (compressional waves). The S waves won't travel through the outer core because it's a liquid, but the P waves will go through it and continue going through the inner core as well.
Is sound louder in gas or solid?
You can hear a sound better in a liquid. This is because the molecules in a liquid are much closer together than the molecules in a gas, so vibrations travel much more easily through a liquid.
Which type of seismic wave can only pass through earths mantle?
There is no seismic wave that can only pass through the Earth's mantle. However S-waves can not travel through earth's outer core because it is a liquid.
What type of scientist analyzes the composition of rocks?
A geologist does that and he/she studies both the liquid and solid materials of earth.
Which structural layer of earths interior have scientists concluded is liquid?
the mantle
What is our risk level from convection currents?
Convection currents are caused by a rising temperature of liquid in the earth's mantle. The risk is that the pressure will build up and, through volcanoes, the liquid will be pushed out. The risk level varies from place to place and is carefully monitored by geologists.
Who concluded that rockets for space flight must be powered by liquid fuel?
Germany
Why do geologists consider the inner core and the outer core as parts of the same layer instead of two separate layers?
because the outer core is liquid and the inner core is solid.
What do longitudinal waves have to do with earthquakes?
The disturbance from an earthquake propagates as a wave. This wave can be either longitudinal or transverse. (Since waves that pass through the Earth's core are always longitudinal, geologists conclude that the Earth is liquid. A liquid won't transport transverse waves.)
Why can you drink through a straw?
because there is a gap throgh it therefore liquid can pass through it (:

What state of matter must be supplied with the most energy to turn it into a gas And why?
Solid, because it goes through a longer process than the Liquid. Thus, the Liquid doesn't need as much energy as a solid.

What is the change from liquid to gas?
To change a gas to a liquid, you condense it.
What body wave can't move through the liquid outer core?
S waves cannot travel through the outer core because they can only travel through solids, and the outer core is liquid.
