The aurora is the luminous emission of atoms and molecules in the polar upper atmosphere that appears as permanent, ringshaped belts called the auroral oval around the north and south geomagnetic poles (see Figure 1). It is associated with a global electrical discharge process that requires about...
Water is one of the primary life forces on the planet, enabling biological life to thrive. It exists in the clouds; in the sea, rivers, and oceans; and even underground! Water circulates between the land, bodies of water, and atmosphere through the water cycle in stages that include ...
What causes major temperature inversions in the atmosphere? What affects air currents and ocean currents? How does wind affect temperature? Explain why this occurs. How does an extratropical cyclone develop? What causes the Gulf Stream? What causes currents?
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 ...
In the atmosphere, light travels through hot and cold air at different speeds. This moving and mixing air associated with high turbulence causes light to bend or refract before reaching your telescope. This causes objects to appear shaken or blurry. ...
Related:Aurora colors: What causes them and why do they vary? "These particles are deflected towards the poles of Earth by our planet's magnetic field and interact with our atmosphere, depositing energy and causing the atmosphere to fluoresce," Billy Teets, the director of Dyer Observatory at...
The Earth atmosphere interface is not associated with a change in phase, only with a change in composition. As you pointed out, this is a discontinuity associated with compositional transition, not phase transition. The proportions of different elements are different between atmosphere and crust. ...
Debris thrown into the atmosphere by an asteroid collision would presumably contain large amounts of iridium, and atmospheric currents would carry this material all over the globe. A search of sedimentary deposits that span the boundary between the Cretaceous and Tertiary periods shows that there is...
In the winter, the jet moves to lower latitudes resulting in greater rainfall for southwestern states while the cool Canadian air causes winter storms in the northern areas.According to the passage, what causes the winds to rise at the tropical latitudes A.Higher temperaturesB.Sinking currentsC....
convection current. Sunlight or reflected light radiates heat, setting up a temperature difference that causes air to move. Shady or moist areas are cooler, or able to absorb heat, adding to the effect. Convection currents are part of what drives the global circulation of theEarth's atmosphere...
