Answer:
The correct answer is option 2. "Scientists use seismometers to measure the earthquake activity that occurs beneath a volcano. They then predict the eruption of that volcano".
Explanation:
A seismometer is an equipment used by scientists to monitor ground's motion, including the earthquake activity that occurs beneath a volcano. These instruments are useful to predict if a volcanic eruption is imminent. By analyzing the length and strength of the ground's motion occurring during earthquake activity near a volcano, scientist could predict if an eruption is about to take place.
Answer:
C. Yes, the force applied to the car affects the motion.
Explanation:
Layer C
Explanation:
The fault break occurred after layer C in the rock sequence.
Layer C is an igneous intrusion through the rock.
To interpret this sequence, we need to apply the law of superposition of strata and cross-cutting .
The law of superposition of strata states that "in an undeformed sequence of strata, the oldest is at the base and the youngest is on top".
Law of cross-cutting states that "intrusions and faults are younger than the rocks they cut through".
- The intrusion is the last even before the fault because it cuts through layers A, B D and E.
- After the intrusion then the faulting event happened.
