how do you find the range of Force that can be applied to a object in rest and still remain motionless, Any number of forces can be applied on an object at rest and still remain at rest ie. roughness of the terrain. Earths rotation about its axis causes moving particles to behave in a way that can only be understood by adding a rotational dependent force. In the friction layer, the turbulent friction that the Earth exerts on the air slows the wind down. How does the surface of the Earth affect the wind? Hardcopy by March 8th on Amazon, Gif Image: View Image in a New Window or In Power Point [Full Screen Mode], Primary References:NCERT Geography,Certificate Physical and Human Geography [Amazon and Flipkart],Spectrums Geography [Amazon and Flipkart]. The winds in the upper atmosphere, 2 - 3 km above the surface, are free from the frictional effect of the surface and are controlled by the pressure gradient and the Coriolis force. Friction has two effects on the wind. Advertisement cookies are used to provide visitors with relevant ads and marketing campaigns. The wind direction follows the direction of change of pressure, i.e. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. Wind is caused by a difference in pressure from one area to another area on the surface of the Earth. List of National Parks of India (106 National Parks in India in 2022), List of Tiger Reserves in India (53 Tiger Reserves in 2022). That force is friction. Boundary Layer Winds: more of friction's impact on low level winds Its greatest effect is near the earths surface and rapidly decreases with height (within lowest 1 km). When we push an initially resting refrigerator with an external applied force, Figure 4. Figure 2. Turbulent drag occurs when Earths surface or objects on it cause resistance to airflow and reduce the wind speed. For starters, the magnitude of the force of friction increases with increasing speed: the faster surface winds blow, the greater the force of friction. directly over the Equator to its maximum value at the poles.

The motionless ocean floor removes momentum from the circulation of the ocean waters.
