What makes up the Earth's lithosphere?

How will you differentiate continental crust from oceanic crust based on their thickness and density?

What do you call the rigid sections of the lithosphere that move as a unit?

One of the consequences of moving crustal plates is the occurrence of earthquakes. Which of the following is a must to perform during an earthquake?

What are the three types of waves released during the earthquake?

What do you call the method of locating earthquake epicenter by using data from three seismological stations?

From the seismogram, the distance to the epicenter can be determined by measuring:

You are asked to locate the epicenter of a recent earthquake. Which correct sequence of events should you follow?

i. Determine the difference in the arrival time of P and S waves.

ii. Use the triangulation method to locate the center.

iii. Obtain data from three different seismological stations.

iv. Determine the distance of the epicenter from the station.

What do you call the point on the Earth's surface directly above a focus or hypocenter, the point where an earthquake originates?

Why is there a need to identify the locations that are prone to earthquakes and volcanic eruptions?

What do you call the major area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur?

How will you relate the distribution of earthquake epicenters with the distribution of active volcanoes around the world?

You are getting ready for school and an earthquake strike, what precautionary measures should be done during the earthquake?
