Earthquakes Question ... Earthquakes have two kinds of waves, P waves and S waves. These waves may someday help scientists develop an early warning system for earthquakes. The P wave (also called the primary wave) is the first wave, and the S wave (secondary wave) travels after it. Scientists can find the location of an earthquake’s epicenter by subtracting the time that elapses between the P and S waves. A convenient way to find the epicenter is to use a graph like the one shown here.

Suppose that scientists record a P wave on a seismic device at 10 minutes.

An S wave reaches the device at 15 minutes (5 minutes later). What is the distance between the recording device and the epicenter of the earthquake? Use the graph to determine your answer.

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
