Winds and ocean currents are caused by ___. A. the moon B. the sun C. the Earth's rotation D. stars 相关知识点: 试题来源: 解析 C。中文解析:风和洋流是由地球的自转引起的。文章中有“Winds and ocean currents are caused by the Earth's rotation.”。
The main causes of ocean currents are wind, the Earth's rotation and differences in water density within oceans. Different types include surface currents, deep ocean currents and tidal currents. The majority of the world's oceans' surface currents are caused by the wind. The most common deep ...
What Causes Ocean Currents? Surface currentsare caused by wind. As the wind changes, the current may change as well. The Earth’s rotation can also affect ocean currents. This causes currents to flow clockwise in the northern hemisphere and counterclockwise in the southern hemisphere. 💡TIP:You...
In a method for acquiring eddy currents that are caused by switched magnetic field gradients and that contain cross-terms, at least the cross-terms can be determined from the selected slice within a short time, by the steps of introducing a spatially expansive phantom into the examination region...
While rip currents are caused by the action of waves they are also affected by the tides. Whether the tide is in or out will vary the depth of water over sandbars, effectively becoming a switch that turns wave breaking on and off as water depth rises an...

When a wave reaches the shore,however,the water does move forward.It surges(前进)onto the shore.This is because the"bottom"of the wave drags on the sand and the"top"continues on,crashing onto the shore.This crashing water is called the surf.Most waves are caused by wind ...
aFluctuations like voltage drops are caused by high starting currents of the motors, while voltage surges are the consequence of the feedback of braking energy into the overhead line. 而电压浪涌是刹车的能量反馈的后果入顶上的线,波动象电压下落是由开始马达的潮流的上流造成的。 [translate] ...
In particular, it is shown that in an inverter-motor system the common mode voltages generated by a PWM inverter, which are attributed to PWM switching harmonics, couple through parasitic capacitances from stator windings to the rotor body and then returns through the motor bearings to the ...
Around 80 percent of all lifeguard rescues are caused by powerful rip currents pulling a swimmer into danger. If you find yourself being pulled out to sea by an unsuspected rip current, you should remain calm, focus on staying afloat and, if you can, swim parallel to the shore. Your ...
