Science, earth sciences.  ---  Air: atmosphere origin, vertical components, horizontal components.  Climate, clouds, storms, wind.  ---  12/30/1992

Science, earth sciences.  ---  Air.  All weather is due to presence of gas (air), inertia of gas, heat and cooling, and moisture.  Heated air rises and moves horizontally, and then slows down.  Moisture is picked up and dropped.  It is like cigarette smoke in a room, except on a grander scale.  ---  12/30/1992

Science, earth sciences.  ---  Dirt.  Love the dirt.  The big brown earth.  (1) What is dirt?  Part rock.  Part clay.  Part dead organic plant and animal matter.  Part live organic plant and animal matter.  Part water.  Part air.  (2) Many people are uncomfortable with dirt.  Many people are dirt-phobes.  (3) Farmers know the land, the soil, the dirt.  Organic farmers know the dirt.  ---  3/25/2006

Science, earth sciences.  ---  Earth.  Components of earth.  Mantle, hot molten core.  ---  12/30/1992

Science, earth sciences.  ---  Water: lakes, oceans, ice, estuaries.  ---  12/30/1992

Science, earth sciences.  ---  Water.  (1) What causes the currents in the ocean?  Is it similar to the wind in the atmosphere?  Heating and cooling.  (2) What causes the tides?  Gravitational pull of the moon.  ---  9/18/1998

Science, earth sciences.  ---  Weather.  You can set the scene by describing the weather.  Wind speed, wind direction, temperature, humidity level, cloud cover, time of year, time of day, and geographic place says it all.  If you say, it was a spring day, about 45 degrees Fahrenheit, with a north wind, low humidity, on a sunny day with few clouds, around four in the afternoon, in New York, that says something.  ---  4/17/2006
