Begin the Interactivity portion of the Earthquake Animation by picking the location of seismometers in three cities of your choice. Each of these seismometers produced a seismogram of the earthquake. Open each location's seismogram, and drag the green line to mark the moment of the arrival of the S-waves. This is recorded in seconds as your S–P value. The S-P value is a measure of the difference in time between the:. a. arrival of the shear body waves and the compressional body waves.
b. shear surface waves and the compressional body waves.
c. arrival of the secondary waves and the primary waves.
d. arrival of the secondary waves and the surface waves.
e arrival of the primary waves and the surface waves.

it is very hard for the climatologists to precisely predict how will the global temperatures be changing so there's lots of models, some of which differ significantly, this is due to multiple factors, and probably the most important is the human activity.

humans have been a key factor in climate change around the globe since the start of the industrial revolution, and in the past few decades the consequences are becoming more obvious. there's lots of emission of pollutants in the atmosphere as well as changing the environment on the surface itself, so it's really hard to predict how will that go in the future because there's some countries that are reducing the damage and are going towards green energy, while others are stubbornly continuing with pollution and damages to the environment.
