Question

Geologists have special tools to help them learn more about how energy is carried in the lithosphere. If a geologist observed that the speed of seismic waves in an area was increasing, what might he infer? a Tectonic plates in the lithosphere have moved. b There is water underground in the area. c The lithosphere is mainly made up of solid rock. d The temperature of the inner core has cooled somewhat.

Answer 1

Answer:

The answer is option A "Tectonic plates in the lithosphere have moved."

Explanation:

Despite the fact that the innovation doesn't exist to go into the entirety of Earth's layers, researchers can even now become familiar with an incredible arrangement about Earth's structure through seismic waves.

Seismic waves are vibrations in the earth that send energy and happen during seismic movement, for example, quakes, volcanic emissions, and even man-made blasts. There are two sorts of seismic waves, essential waves and optional waves. Essential waves, otherwise called P waves or weight waves, are longitudinal pressure waves like the movement of a smooth . Auxiliary waves, or S waves, are more slow than P waves. The movement of auxiliary waves is opposite to the heading of the wave travel, like the movement of energetically shaking a rope
