Scientists believe that this layer of the Earth is made of hot liquid iron and nickel?
The outer core.
Which term refers to the ridged layer of Earth that is about 100 km thick and generally less dense than the material below it?
The Lithosphere is the ridged layer of Earth that is about 100 km think and generally less dense than the material below it. This layer is the tectonic plates the move along on the anthesphere.
What is just below the Earth's crust?
The D" layer (pronounced D double prime layer) forms the base of the Earth's lower mantle. Below this lies the outer core. This boundary zone is marked by a seismic discontinuity known as the Gutenberg discontinuity.
What is the discontinuity layer?
In geology, a subterranean interface at which seismic velocities change.
What year do scientists think the ozone layer will have rebound?
Scientists hope the ozone layer will have recovered by around 2050.
How can seismic waves be used to help scientists know what type of material each layer of earth is made of?
Seismic Tomography is the most popular technique used to find the Earth's sub-surface characteristics.
How did scientists determine Earth has layers?
Scientists determined that the Earth has layers through studying how seismic waves travel. These seismic waves differed depending on how thick the layer was.
How can seismic waves be used to help scientists know what type of material layer of the earth is made of?
A+ answer: all waves change directions as they travel through different materials
How do scientist learn about the mantle and core of earth?
Scientists learn about the layers deep within the Earth's crust by studying how seismic waves travel through the Earth. If there is an earthquake somewhere, seismographs in many locations will record it. By looking at the time of arrival of the main set of waves, and how the frequencies of the waves are arranged within the set, scientists can learn about the density and other properties of the layers. The relative differences in arrival times of the S and P seismic waves at several recording stations tell scientists about the different speeds those waves were traveling at, which in turn gives information about the density of the material the layer is made of, and how thick the layer is in several directions.

What layer of the earth will a seismic wave travel trough faster?
The mantle

How have seismic wave studies helped scientists determine the structure of Earth's interior?
The speed of the waves that travel through the interior can tell the density of each layer of the Earth. Some waves can make it through certain layers, but not others.
Scientists have been able to determine the composition of earths layer by what?
making inferences based on data from seismic waves.
What layer of the earth do scientists know most about?
the crust because that is the layer we live on so scientists can study it more thourouly
Which layer has malted material?
There are 4 different layers that the Earth is composed of. The layer that has the melted material is the core layer. The core layer is also the hottest layer.
How do seismic waves help scientists understand earth's interior?
The speed of the waves that travel through the interior can tell the density of each layer of the Earth. Some waves can make it through certain layers, but not others.
