What is this pie chart on below showing?
patriot [66]
I think it's showing how much those things are being used. For example, JAVA is being used 7.7% out of the total amount. The total amount is all of the percents added so : 30.8+30.8+15.4+7.7+7.7+7.7=100.1. About 100. JAVA is 7.7 out of 100. JS is 30.8 out of 100. CSS is 15.4 out of 100. The others the same way

Why do scientists need to study seismic waves to analyze the interior of the earth and the layers of the earth?
DaniilM [7]

Answer:

Answer 1:

Seismic waves, the waves of energy that travel through the Earth as a result of an earthquake can tell us a lot about the internal structure of the Earth because these waves travel at different speeds in different materials. There are two types of waves that travel through the Earth: p-waves and s-waves.

P- waves are faster and they can travel through both solids and liquids. S-waves are slower and cannot travel through liquids. For both kinds of waves, the speed at which the wave travels also depends on the properties of the material through which it is traveling.

Scientists are able to learn about Earth’s internal structure by measuring the arrival of seismic waves at stations around the world. For example, we know that Earth’s outer core is liquid because s-waves are not able to pass through it; when an earthquake occurs there is a “shadow zone” on the opposite side of the earth where no s-waves arrive. Similarly, we know that the earth has a solid inner core because some p-waves are reflected off the boundary between the inner core and the outer core. By measuring the time it takes for seismic waves to travel along many different paths through the earth, we can figure out the velocity structure of the earth. Abrupt changes in velocity with depth correspond to boundaries between different layers of the Earth composed of different materials.
