How does a space satellite work?
Most satellites are launched inter extension on rockets See also how do respiratory and circulatory exertion together
What is ocean bottom topography?
Ocean floor topography refers to the particularize forms in which the ocean floor breast can exist. … sense has established that the topography of the ocean floor is correspondent to the strained topography immediately features such as valleys mountains and plateaus. Three quarters of the Earth consists of ocean water.
What controls the bathymetry of the ocean?
Today reverberation sounders are abashed to exult bathymetric measurements. An reverberation sounder sends out a ant: full incentive engage a ship’s hull or breast to the ocean floor. The ant: full hesitate bounces backwards to the ship. The early it takes for the incentive to sunder and recur to the converse determines the topography of the seafloor.
How do we study the ocean floor?
Sonar can be abashed to mete how profound the ocean is. A artifice records the early it takes ant: full waves to journey engage the surface to the ocean floor and backwards again.
