Q:

What are the interactions between the atmosphere and hydrosphere?

A:

Interactions between the atmosphere and hydrosphere involve creation of water-related weather activity, such as rainfall, snowstorms, hurricanes and monsoons. The atmosphere contains five layers, which perform separate functions. The atmosphere performs many important duties, including producing winds and temperature that influences seasonal temperatures, and interacts with all systems on Earth, including the lithosphere and biosphere.

While the atmosphere stores water molecules, moisture and water form in the hydrosphere. The hydrosphere includes all bodies of water on Earth, ranging from underground reservoirs and basins to streams, rivers, oceans and lakes. It also includes solid and gaseous water, such as ice and water in volcanoes and hot springs. Regardless of source, however, water from the hydrosphere evaporates into the air and reaches the atmosphere in the same way since water in the hydrosphere and air in the atmosphere move constantly. In the water, currents and waves create movement, much like winds in the atmosphere. The winds from the atmosphere affect movement of water, depending on direction, force and temperature. Water that heats from the sun evaporates into the atmosphere, where it resides as water vapor. When cooled, the heavier water molecules release, causing rain, snow, sleet and other forms of precipitation.

    What color is the sky?

    A:

    On a clear day the sky is blue to deep blue. At dawn and dusk the stretch of sky nearest the sun changes to shades of red, orange and yellow. The color of the sky is primarily determined by the way air molecules scatter light relative to the sun's angle.

    What is the benefit of the ozone layer?

    A:

    The ozone layer absorbs most of the biologically damaging ultraviolet radiation from the Sun, allowing only a small amount to pass. Through UV absorption, it creates a source of heat that defines the temperature characteristics of Earth's stratosphere. Left unfiltered, certain frequencies of UV radiation would more easily penetrate the protective coverings of organisms, causing severe damage to DNA molecules.

  • Q:

    How does altitude affect climate?

    A:

    Altitude affects climate in that the higher up you get, the more the temperature drops. The temperature goes down roughly 4 degrees Fahrenheit for every 1,000 feet you climb. Altitude is the subject's distance from the sea. This is why a lot of high-up places such as mountaintops often get snow for most of the year when other places do not, no matter how low the temperature drops.

  • Q:

    What are the ingredients in the air we breathe?

    A:

    The air humans breathe is made up of about 78 percent nitrogen, 21 percent oxygen, and 1 percent carbon dioxide and argon. Trace gases include krypton, methane, neon, helium and hydrogen. Air generally contains trace amounts of water vapor, as well, with greater concentrations occurring near sea level.
