from News and Views discusses the observation and analysis of submarine volcanic eruptions. Volcanism underwater is unalike volcanism on land due to the differing qualities of water and air. Air is not as dense as water; the properties of air allow for larger eruptions than those that occur underwater (Mitchell 444). Pressure on the ocean floor does not allow water or gasses to escape from lava. This causes the eruption to have less of an impact underwater than it would if it were on land. Water’s

greenhouse effect in is the entrapment of the sun’s heat energy in the earth’s atmosphere. Greenhouse gases such as carbon dioxide‚ water vapor‚ methane‚ and nitrous oxides are all gases that contribute to this phenomenon. Carbon dioxide is the most abundant greenhouse gas while water vapor the least harmful gas makes up less than one percent of the gases in the atmosphere. These greenhouse gases are produced naturally by the earth for example carbon dioxide‚ and methane is produced from the waste

INTRODUCTION [SLIDE 2] Many chemical compounds found in the Earth’s atmosphere act as “greenhouse gases.” These gases allow sunlight to enter the atmosphere freely. When sunlight strikes the Earth’s surface‚ some of it is reflected back towards space as infrared radiation (heat). Greenhouse gases absorb this infrared radiation and trap the heat in the atmosphere. Over time‚ the amount of energy sent from the sun to the Earth’s surface should be about the same as the amount of energy radiated back

There is some truth to the statement "what gets measured gets done" with respect to the work environment‚ discuss.

However‚ I would argue that the sentence in itself is incomplete. Between the ‘measuring’ and ‘getting done’‚ mangers need to insert both critical analysis of the measurements
