What do scientists study to learn about the temperature inside the earths crust?
Scientists study seismic waves to learn about the temperature inside the Earth's crust. By analyzing the speed and direction of these waves as they travel through different layers of the Earth, scientists can infer information about the temperature and composition of the Earth's crust.
Why do scientists only have theories about the composition of the mantle and core but they know the exact composition of the crust?
The Earth's Crust is what we stand on, so it's within easy reach of scientists. The mantle and core, by contrast, are deeper inside the planet, where no drill or human being can reach.This means that we must learn about the mantle and core of our planet with less direct methods. We have a pretty good idea of the composition and density of the Earth's mantle and core by studying the effects of earthquakes, by measuring the behavior of earthquake waves as they travel through the Earth.
How do you know that the earth is in layers?
Scientists have determined the layers of the Earth by studying seismic waves from earthquakes. These waves travel through the Earth at different speeds and provide information about the density and composition of the different layers beneath the surface. By analyzing this data, scientists have been able to deduce the Earth's structure and layers.
How is Earth's crust and boiling milk alike?
Both Earth's crust and boiling milk form a thin, outer layer with a relatively lower density compared to what lies beneath them. Additionally, they can both experience a form of movement - the Earth's crust in the process of plate tectonics, and milk in the boiling process as it churns and bubbles.
What are the zone between core and crust?
The zone between the core and crust of the Earth is the mantle. It is a layer of solid rock that extends about 1,800 miles (2,900 kilometers) below the Earth's surface. The mantle is made up of silicate minerals and is responsible for convection currents that drive plate tectonics.
What do we know about what it looks like beneath the earth's crust?
You will never know what it look like under the earth's crust :)
How do scientists know when the crust is moving if they cant see it?
They don't know, they just guess
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

What is the composition of the crust under the continents How do you know?
The crust under continents is primarily composed of granitic rocks, which are rich in silica and aluminum. We know this through studies of rock samples collected from the Earth's surface and seismic data that provide information about the composition and structure of the crust beneath continents. Additionally, drilling projects such as the Mohole project have allowed for direct observations of crustal composition at depth.
I know there is water under land But what is under water?
If we look beneath water, no matter how deep, we will always find the rock of the crust of the earth. You might have heard the term "ball of rock" applied to the earth, and the crust is the outer covering of that ball of rock. All of the world's oceans sit on top of the crust of the earth.
Why does molten rock escape from under the earths surface in certain places?
Molten rock, or magma, escapes from beneath the Earth's surface through volcanic eruptions due to the build-up of pressure from the movement of tectonic plates. This pressure can push the magma upwards through cracks or weaknesses in the Earth's crust, resulting in volcanic activity.
Why do scientists to investigation?
To know about scientists life
Why are map showing locations of past earthquakes useful to scientists?
Earthquakes happen when the Earth's crust shifts violently. So if we know that an earthquake has happened in California, then scientist know that the crust under California is unstable, therefore making earthquakes more likely to happen there. Earthquakes can happen anywhere, but the tend to happen repeatedly in certain spots
What is the crusts thickness?
There are two types of crust's. I dont know which one you are talking about, but it is probably the continental crust. The other type of crust is the Oceanic crust. The first continental crust is about 4-7 miles (6-11 km) thick and mainly consists of heavy rocks, like basalt. The Continental crust is thicker than the Oceanic crust, about 19 miles(30 km) thick. It is mainly made up of light material like granite.
