TEACHER BACKGROUND: NATURAL CLIMATE CHANGE

TEACHER BACKGROUND: NATURAL CLIMATE CHANGE . The NATURAL variability and the CLIMATE fluctuations of the CLIMATE system have always been part of the Earth's history. To understand CLIMATE CHANGE fully, the causes of CLIMATE CHANGE must be first identified. The earth's CLIMATE is influenced and changed through NATURAL causes like volcanic eruptions, ocean currents, the Earth's orbital changes, solar variations and internal variability. Volcanic eruptions - The main effect volcanoes have on the CLIMATE is short-term cooling. Volcanic eruptions pump out clouds of dust and ash, which block out some sunlight.

Earth's surface. Measure and draw a line 80 mm from the Earth's surface. Label this layer mesosphere. Color it red. Draw pictures to help show characteristics. Draw the ionosphere. This is the fourth layer of the atmosphere. It extends 80km-400km from the surface. Label it the ionosphere and color it pink.

If the temperature is high, the body sweats in order to cool down. Since the process of sweating is done to stop the temperature change, this is a negative feedback.

TEACHER BACKGROUND: SPECIFICS OF HEAT TRANSFER

gml.noaa.gov

In a new scenario, a metal can containing hot water is placed in a Styrofoam cup containing cold water. Heat is transferred from the hot water to the cold water until both samples have the same temperature. The transfer of heat from the hot water through the metal can to the cold water is referred to as conduction.

corals display different sensitivities to changes in aragΩ and SST [Reynaud et al., 2003]. Considering that both these environmental parameters are likely to change considerably in the future, additional experiments on a variety of differing coral species will be crucial to obtain a better understanding of future coral reef stability.

The associated surface tension gradient draws surfactant a finite distance up the jet, prompting two salient alterations in the jet surface. First, the surfactant suppresses surface waves, so that the base of the jet surface assumes a cylindrical form (Figure 6). Second, the jet surface at its base becomes stagnant: the Marangoni stresses
