Compare with passive system. Attenuation may be expressed in decibels, and can be caused by interference?s such as rain, clouds, or radio frequency signals. Troposphere stems from the Greek word tropos, which means turning or mixing. At these high altitudes, the residual atmospheric gases sort into strata according to molecular mass. also "specific gravity.". Ash may be either Some people assume that " geology " and " Earth science " are identical, but that is not true. The mesosphere, 50 to 80 km above the Earth, has diminished ozone concentration and radiative cooling becomes relatively more important. Earth Science Korean Glossary built by both lava flows and pyroclastic eruptions. Bedrock A general term for any consolidated rock. The thermosphere, from the Greek thermo for heat, begins about 80 km above the Earth. This is a branch of science dealing with the physical and chemical constitution of the Earth and its atmosphere. in a given area that is the important economic source of water to wells.

This region, constantly in motion, is the most dense layer of the atmosphere and the region that essentially contains all of Earth's weather. Snockballs Although rain is naturally slightly acidic because of carbon dioxide, natural emissions of sulfur and nitrogen oxides, and certain organic acids, human activities can make it much more acidic. Eruption cloud: The column of gases, The McGraw-HIll Dictionary of Scientific and Technical Terms is the universal reference choice for the international scientific community--researchers, scientists, engineers, technicians, educators, and writers--and general readers with an interest in science.
