Derek's experiment best demonstrates the effects of gravity, that force made the water go down and hit the ground, the effect of that was a depression.
The definition of Hydrosphere is all the water of earth surface, so the water represents Hydrosphere.
The definition of Geosphere is the surface of Earth, when the water fell down and touched the ground it caused an interaction between Hydrosphere and Geosphere.

Answer:
find possible answers to problems
Explanation:
Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.
Science is applied to many fields in the world such as medicine, information technology, cybersecurity, engineering, environmental etc.
Basically, knowing how to apply science simply means a scientist understands the appropriate method or technique to be used in the application of a technology such as when solving a problem.
Creativity implies being able to use an idea to proffer solutions to a problem in an intelligent manner.
Hence, a scientist should be creative in order to find possible answers to problems.
The displacement of an object is obtained by taking out the area of the rectangle plus the area of the triangle under the line.
<h3>What is acceleration?</h3>
Acceleration is defined as the rate change of velocity with time.
acceleration a = (Δv) / (Δt)
Suppose the initial position of an object is zero, the starting velocity is 3 m/s and the final velocity was 10 m/s. The object moves with constant acceleration.
In velocity time graph, the slope determines the acceleration and the area under the curve gives the value for the displacement.
Thus, the displacement of an object is obtained by taking out the area of the rectangle plus the area of the triangle under the line.

If it starts at rest the initial velocity is 0.
For an acceleration, a, and time, t, the velocity is v=at. Since at t=4, v=7, then a=7/4=1.75m/s^2
