Document Summary
Earth intercepts only a small portion of the sun"s radiation. The sun"s energy drives the hydrologic cycle and all weather phenomena on earth. Nearly all energy available at earth"s surface comes from the sun. 78% nitrogen, 21% oxygen, 1% water vapour, carbon dioxide, and other trace gases. Water vapour in the atmosphere results in cloud development and formation of precipitation, water vapour comes from evaporation for the oceans. All weather is confined in the troposphere. Ozone layer protects us from the sun"s harmful uv rays, found in the stratosphere. Prefix described the height of the cloud: high cloud: cirro, mid-level cloud: alto, low cloud: strato- Suffix describes its appearance: puffy: -cumulus, flat: -stratus. Question on the midterm: be able to name a cloud. Clouds that produce precipitation contain nimb in their name, examples: nimbostratus- prolonged, light precipitation, cumulonimbus- thunderstorm cloud. A front marks the boundary between two air masses.
