It states that layers of sediment are originally deposited horizontally due to the effects of gravity.
Answer: 4500 metres
Explanation:
Echo is a reflection of sound wave. It is the sound heard after it has been reflected off the surface of a wall or cliff.
Time = 6 seconds
Speed of sound in water = 1500m/s
distance =?
From the relationship ;
Speed = distance / time
Distance = speed * time
Distance = 1500 * 6 = 9000 metres
Distance here represents the total distance traveled by the pulse that is distance to the seafloor and back to the surface.
Therefore the depth of the water is given by;
Depth = distance / 2
Depth = 9000 / 2 = 4500metres.

In a region with a high pressure system that later changes to a low pressure system, there shall be experienced stormy weather.
This prediction comes from the fact that low pressure systems are set to experience warm moist air that brings about stormy weather with strong winds.
