Answer: Geologists map out <em>data </em>from previous earth quakes to determine earthquakes risk.
Explanation:
Geology is the study of earth. Also, it is the study of how Earth's materials, structures etc are changed over time.
Geologist is a scientist who studies the structure of earth, rocks, soil, fossils and earthquake. So, they map out the data from previous earthquakes to determine earthquake risk.
C. The average acceleration is positive and smaller in magnitude than the initial acceleration.
<h3>
What is average velocity?</h3>
Average velocity is defined as the change in position or displacement (∆x) divided by the time intervals (∆t) in which the displacement occurs.
a = Δv/Δt
where;
- Δv is change in velocity
- Δt is change in time
a = (250 - 248) / (70 - 40)
a = 0.067 m/s²
Thus, we can conclude that the average acceleration is positive and smaller in magnitude than the initial acceleration.
