Activity 6: CHECKED MATE Directions: Put a CHECK () before the statement that reveals the information acquired by seismic waves about the interior of the earth and CROSS (X) if the statement does not mention seismic waves information about the interior of the earth.

1. Seismic waves are travelling with depth; they move faster in denser materials

2. Foreshocks are small tremors that precede a massive quake

3. When a wave arrives late at the seismograph it means it passes through a hot and semi-fluid part of the earth.

4. The S-wave cannot penetrate the Core-Mantle boundary and the P-waves are refracted in the molten layer of the region of outer core.

5. The occurrence of earthquakes cannot be predicted accurately

6. The shadow zone develops on the opposite side of the earth.​
