Document Summary
Climate : broad composite of the average condition of a region, measured by direction and strength. Short term (hourly, daily, weekly) fluctuations in atmospheric conditions. Hypothesis: a theory that has passed a number of tests and held up against all of them, long term scale >year or meteorological variables. Weather: however, we can never know 100% for sure so it is known as a hypothesis. Any theory that succeeds in explaining a wide array of observations over a period. Major components of climate system serious testing it cannot be considered a hypothesis. E. x. volcanic eruption adds particles to the air that cause local cooling. Theory: created from an observation, a proposed reason for that observation, without. Response: climatic changes resulting from climate forcing. Scientists use celsius and kelvin to measure climate changes. Earth scientists date rocks using isotopes (e. x. uranium) The age of the earth is . Dates the time when cyanobacteria began photosynthesizing and creating.
