Knowledge of Earth's plate tectonics allows seismologists, geologists, and various other scientists to predict what the face of the planet will look like in future, and what it has looked like in the past.
Scientists learn about the layers deep within the Earth's crust by studying how seismic waves travel through the Earth. ... 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.
Geologists and other related Earth scientists have estimated the age of the Earth to be approximately 4.65 Billion years old based on a wide variety of scientific experiments and data.
Severals methods are all combined to give the scientist info on the layers of the Earth. For example they study the influence of the earth on orbits of the moon and other planets (mass distribution of the earth, mass density). They study the way seismic waves go through the earth which gives knowledge of layers. They use wave to sound. They examine sample of earth.
a earthquake can really start anywhere but it is usually started at the earths core (middle). Other names are the epicenter which is were the earthquakes starts at the earths surface. The focus is where it begins inside the earth.....
Studying the earth helps scientists to understand other planets since the earth is part of the solar system. Scientists use the features of the earth to compare them with what other planets hold.
A geophysicist.
The moon can be seen anywhere from Earth.
Scientists look to the seismic waves to reveal the Earth's interior.
Ecologists study how living organisms and the earth interact with each other.
They had believed that none of the noble gases would form any compounds with other elements.
dust and ice and other partcials
We may possibly know how Earth was created.
We have no direct evidence yet of life anywhere other than Earth.
A progam to study Earth by using satellites in the same way that scientists study other planets.
It can help by them comparing and contrasting.
Because they are carved out
