根据第二段的 “One type of rip current, known as a channel rip current, forms when there are gaps between breaking waves.(一种类型的离岸流,被称为通道离岸流,当破碎波之间存在间隙时形成)”及“The darker corridor of the escaping water acts like a conveyor belt, moving water, unsuspecting ...
and fall with the tides,and currents flow below the surface.Although it looks as if the water in a wave is moving across the surface of the ocean,it is not.The water is actually moving up and down.This is why an object on top of a wave will bob up and down,but ...
a school.As you know, schooling diminishes a fish's chance of being singled out by a predator, and it helps fish detect food and find a mate, among other things.Now, tuna do form schools after congregating under floating objects, but what really supports the hypothesis is evidence of scho...
Why does marine phytoplankton calcify? Crucial To The Food Chain: Plankton are microscopic organisms that live in the oceans and that cannot generate movement on their own. They move with the ocean currents, and are crucial to the marine food chain and also to the food chain of all animals ...
Why does water move into the ground to create groundwater? Why are diatom shells found in ocean floor sediments? Why is it easy to slip when there is water on the floor? Why does ocean salinity matter? Why is rapid beach erosion a problem?
In the oceans, plastic is a leading form of litter. In 2015, National Geographic reported that there were5.25 trillion pieces of plastic debris in the oceanat that time. Plastic can absorb toxic chemicals from the environment and transport them to other environments as currents move the plastic...
inland hub, a process which is known as drayage. The drayage piece of the supply chain is long. It can be a day, a day and a half, two days. [Narrator] So why does it take that long to move our container essentially a half mile?
oh my god. is that actually the best move in the position? that move violates most human chess principles that we have been brought up with? you shouldn't push ponds in front of your king. you should not weaken an area of the board where you can't claim any advantage. how does ...
The consistent direction of the wind from the northeast creates a region of heavier rainfall on the Caribbean slopes and over the central mountains. The air continues to move to the southwest, but by the time it reaches Guanacaste, Nicoya and the Pacific much of the moisture has been removed...
These streams eroded through the jumbled sediment that the glacier scraped up the valleys as it advanced. Since this sediment is carried in water, the water sorted it depending on the speed of the stream. Fast-moving water carries a lot of energy and can move gravel and coarse sands. Slow...
