Alternatively, weather kits will let your child play the role of a real meteorologist as he or she gains hands-on experience tracking and testing the Earth�s climate changes. Observing local weather patterns will help develop these concepts before expanding to a national or worldwide comparison. It has been said, for example, that a butterfly flapping its wings today in China could produce (or prevent) tornadoes two weeks from now in Kansas. This has the effect, though, of creating "boundaries" between regions of ocean where the #1 wave group suddenly switches to second place.

Paleoclimatology Data - Climate variability and climate change data, research, and information Peering Into the Storm: NASA's Exploration of Hurricanes - Webcast of a presentation at the Library of Congress by Dr Cold air is more dense (has a greater weight per unit volume) than warm air. If the air is unconfined and heated — as would be the circumstances in the atmosphere — the density of the gas decreases (i.e. gets lighter). This is because the molecules in the air spread out when heated, causing air pressure to decrease. Heating the air causes the air balloon rise because the heated air is lighter than the colder air around it That lets the area around the North Pole get colder. In the summer, the North Pole is pointed more toward the Sun, and so the part of the Earth near the North Pole gets more direct sunlight, and becomes warmer download. The map also shows low- and high-pressure centers and fronts. This cold front is likely to move toward the northeast over the next couple of days. How could you use this information to predict what the weather will be on the East Coast? Instead of air pressure, weather maps may show other weather conditions. For example, a temperature map might show the high and low temperatures of major cities One serious problem that can occur during a geomagnetic storm is damage to Earth-orbiting satellites, especially those in high, geosynchronous orbits. Communications satellites are generally in these high orbits. Either the satellite becomes highly charged during the storm and a component is damaged by the high current that discharges into the satellite, or a component is damaged by high-energy particles that penetrate the satellite , cited:

Does your child have different achievement levels for math and language arts? Time4Learning lets you set each individual subject at the appropriate graded level, making this curriculum great for special needs and gifted students epub. Earth is the only planet we know to be capable of sustaining life. It is our lifeboat in the vast expanse of space , source: Experiment to demonstrate why some fumaroles produce more steam than others Isotherms show temperature gradients and can indicate the location of a front. The 0°C (32°F) isotherm will show where rain is likely to give way to snow. Isobars are lines of equal average air pressure at sea level. Closed isobars represent the locations of high and low pressure cells. High pressure cells are shown as Hs and low pressure cells as Ls. A thick, brown dashed line is often placed inside a long low pressure trough ref.: Understand important science concepts and principles. 4. Communicate effectively using science language and reasoning. 5 ref.:
For example, if average global temperatures continue to increase as they have in recent decades, water that is currently trapped as ice in the polar ice sheets will melt, causing a rise in sea level. Water also expands as it gets warmer, further exacerbating sea level rise , cited: Read more In the second part of this field campaign, scientists will visit the Pacific Ocean southwest of Hawaii where ocean salinity concentrations are driven by precipitation Compare the similarities and differences of planets to the stars in appearance, position, and number in the night sky. c download. Alien Pen Pals - Students write a friendly letter to an alien informing it about the planet Earth. Students use editing skills and brainstorming skills to produce a final product ref.: Most years trade winds blow steadily from South America and west across the Pacific pushing surface coastal waters westward. This creates an upswelling of cool water. When the trade winds do not blow, the waters warm up. This warm water gradually spreads partway across the Pacific and as far north as California and Washington The star will attain an energy balance so that the production of energy by fusion equals the upward heat flow, which in turn equals the energy emitted into space. The size and color of the star reflect the balances needed. g.* Students know how the red-shift from distant galaxies and the cosmic background radiation provide evidence for the �big bang� model that suggests that the universe has been expanding for 10 to 20 billion years Tornadoes occur over land and hurricanes occur over sea Eutrophic lake=A lake characterized by abundant dissolved nitrates, phosphates, and other plant nutrients and by a seasonal deficiency of oxygen in bottom water pdf. Relate the temperature of the air to the temperature one meter underground. You will need to dig a hole one meter deep and bury a plastic tube in the hole
As visible light exits the prism, it is refracted and separated into a display of colors. A rainbow is an example of both refraction and reflection. Sunlight is first refracted when it enters the surface of a spherical raindrop, it is then reflected off the back of the raindrop, and once again refracted as it leaves the raindrop ref.: Alpha Centauri=The closest bright star to our solar system. Our Sun's corona can only be seen during a total solar eclipse. Alternative energy resources=All energy resources other than fossil fuels and nuclear fission; including solar energy; hydroelectric power; geothermal energy; wind energy; biomass energy; tidal, wave, and heat energy from the seas; and nuclear fusion ref.: Correlate changes with rainfall or other factors. 13. Relate the temperature of the air to the temperature one meter underground. You will need to dig a hole one meter deep and bury a plastic tube in the hole. Be sure to keep the tube plugged so that air cannot circulate within the tube when you are not taking measurements. 14. Use a thermometer to record the air and water temperatures in a pond or stream However, weather is not limited to planetary bodies. A star's corona is constantly being lost to space, creating what is essentially a very thin atmosphere throughout the Solar System. The movement of mass ejected from the Sun is known as the solar wind. On Earth, the common weather phenomena include wind, cloud, rain, snow, fog and dust storms Students know how the composition of Earth' s atmosphere has evolved over geologic time and know the effect of out-gassing, the variations of carbon dioxide concentration, and the origin of atmospheric oxygen. During the early history of the solar system, strong solar winds drove the primordial atmosphere away. This atmosphere was then replaced by a combination of gases released from Earth (out-gassing), mostly through volcanic action, and by bombardment of materials from comets and asteroids , source: Also the thinnest layer in sedimentary rocks, commonly ranging in thickness from a centimeter to a meter or two Solar storm clouds such as coronal mass ejections (CMEs) sweep aside cosmic rays when they pass by Earth. During Solar Maximum, CMEs are abundant and cosmic rays are held at bay. Now, however, the solar cycle is swinging toward Solar Minimum, allowing cosmic rays to return. Another reason could be the weakening of Earth's magnetic field, which helps protect us from deep-space radiation , cited: Lessons in this chapter are organized into the following sections: Humidity, clouds, and precipitation � Students are introduced to the water cycle, and how it relates to energy. Students will be required to list the basic forms of precipitation and how eat one forms. Students conclude the lesson by discussing relative humidity and dew point, and how they relate to the formation of clouds and precipitation ref.: This weather may be present over a large area. Winds usually blow parallel to the front, but in opposite directions. Shear stresses result when objects are pushed past each other in opposite directions. After several days, the front will break apart , source:
