Earth science module 3

Equipment[ edit ] STS mission specialists working on robotic equipment in the US lab As with the European and Japanese laboratories of the station, payloads inside Destiny are configured around International Standard Payload Racks ISPRsthat can be removed or reconfigured for various experiments and equipment. Destiny can hold up to 13 payload racks with experiments in human life science, materials research, Earth observations and commercial applications.

You have learned about these orbital changes in the Temperature over Time module. These conditions for the northern latitudes favor somewhat higher temperatures, but also more water vapor in the air — causing more snowfall.

A relatively cool summer for the northern latitudes favors less melting of winter snow and glacier formation. The figure above shows the alignment of each of the orbital changes to the glacial and interglacial periods.

The interplay of the three orbital cycles affects the amount of solar radiation received at different latitudes over the year. Microsoft Clip Art Volcanic eruptions discharge carbon dioxide, but they may also emit aerosols, such as volcanic ash or dust, and sulfur dioxide. Aerosols are liquids and solids that float around in the air.

They may also include soot, dust, salt crystals, bacteria, and viruses. Aerosols scatter incoming solar radiation, causing a slight cooling effect. Volcanic aerosols can block a percentage of sunlight and cause a cooling that may last for years.

This was possibly the largest known eruption in the history of human civilization. Snow fell in the northeastern United States and Canada in June, causing regional losses of crops, food shortages, and increased mortality.

Relatively cold years also followed other famous volcanic eruptions such as the eruption of Krakatau also in Indonesia and eruption of Mount Pinatubo in the Philippines. The larger particles settle after a few days while the sulfur dioxide combines with water vapor to from sulfuric acid H2SO4 and sulfate particles, known together as sulfurous aerosols.

Winds transport these sulfurous aerosols around the planet in easterly or westerly directions. For this reason, volcanoes that erupt at lower latitudes closer to the equator are more likely to cause hemispheric or global cooling.

Volcanoes that erupt at higher latitudes closer to the poles are less likely to cause cooling because the sulfurous aerosols are confined to wind patterns surrounding the poles.

Variation in Solar Radiation Sunspots. The energy emitted by the sun only varies by 1. This change in solar radiation is related to the number of sunspots.

Sunspots appear dark because their temperature is lower than the surrounding area. Approximately every 11 years, the number of sunspots changes from a maximum number to a minimum number. The sun emits slightly more radiation during active periods of sunspots. Because the sunspots are suppressing heat, the heat flows to surrounding areas causing these regions to be brighter than normal, radiating more heat.

While more sunspots may contribute to warmer global climate, less sunspots appear to be associated with a cooler global climate.Authors of this module. Piklu Gupta: At this time of writing this module Piklu was a lecturer in German Linguistics at the University of Hull, UK.
