FAQ: Northern Africa, Southwestern Asia, And Southwestern North America Experience What In Common?

How is energy routinely transferred from low latitudes to high latitudes?

How is energy routinely transferred from low latitudes to high latitudes? Land experiences less evaporation, so less energy is lost as latent heat. At a given latitude, sunlight spreads out over land more than it does over water. Land experiences less evaporation, so less energy is lost as latent heat.

Which substance is the best transmitter of solar energy?

Nearly 95% of all solar panels made in the US for residential use are made of crystalline silicon. Crystalline silicon is an excellent substance to transmit solar energy because the cells align in a crystal structure; the more perfect the structure, the more efficient it is at transmitting energy.

Which location is associated with persistent upwelling of cold water to the ocean surface?

Upwelling is the natural process which brings cold, nutrient-rich water to the surface. A huge upwelling regularly occurs off the coast of Peru, which enjoys a large fishing industry as a result. Upwelling is a process in which currents bring deep, cold water to the surface of the ocean.

Which two factors determine the overall temperature of Earth’s atmosphere?

The two most important factors in the climate of an area are temperature and precipitation. The yearly average temperature of the area is obviously important, but the yearly range in temperature is also important. Some areas have a much larger range between highest and lowest temperature than other areas.

Why does convection occur in the troposphere but not in the stratosphere?

Why are these temperature profiles different? Convection causes heating in troposphere because it drops in temperature with altitude, but has a relatively high density of air. The stratosphere has no weather because convection cannot happen because the air gets hotter in this layer as you go up in altitude.

Which substance is the best transmitter of heat?

Diamond is the leading thermally conductive material and has conductivity values measured 5x’s higher than copper, the most manufactured metal in the United States. Diamond atoms are composed of a simple carbon backbone that is an ideal molecular structure for effective heat transfer.

What is the most significant anthropogenic greenhouse gas quizlet?

Major greenhouse gases include carbon dioxide, methane, nitrous oxide, and various synthetic chemicals. Carbon dioxide is widely reported as the most important anthropogenic greenhouse gas because it currently accounts for the greatest portion of the warming associated with human activities.

What happens to most of the incoming solar energy on Earth?

About 23 percent of incoming solar energy is absorbed in the atmosphere by water vapor, dust, and ozone, and 48 percent passes through the atmosphere and is absorbed by the surface. Thus, about 71 percent of the total incoming solar energy is absorbed by the Earth system.

What is the albedo of the Earth system?

Using satellite measurements accumulated since the late 1970s, scientists estimate Earth’s average albedo is about about 0.30.

Which of the following would be a reason why land heats faster than water?

Land surfaces absorb much more solar radiation than water. Water reflects most solar radiation that reaches its surface back to the atmosphere. Since land absorbs more solar radiation the land surface retains more heat as do the vegetation for energy. Thus, land surfaces warm more quickly than water.

Where would be the most likely place to find a subtropical high?

Subtropical high, one of several regions of semipermanent high atmospheric pressure located over the oceans between 20° and 40° of latitude in both the Northern and Southern hemispheres of the Earth.

Where in the oceans does downwelling occur?

Where does most downwelling occur? Most downwelling happens at the poles. There, cold air chills the water. The water brought in by the surface gyres is pretty salty already, because it comes from the tropics, where evaporation increased salinity.

What factors influence the direction that ocean currents take?

Winds, water density, and tides all drive ocean currents. Coastal and sea floor features influence their location, direction, and speed. Earth’s rotation results in the Coriolis effect which also influences ocean currents.
