The Water Cycle for Kids and Students. The water cycle describes how Earth's water is not only always changing forms, between liquid (rain), solid (ice), and gas (vapor), but also moving on, above, and in the Earth.

Extreme Weather on Our Planet

Activate students’ prior knowledge about extreme weather on Earth.Ask: What do you know about extreme weather on Earth? Encourage students to think about weather they have experienced, read about, or seen on TV or in the movies. Have students brainstorm a list of weather-related words and phrases as they “pass the marker.” Start the process by writing one weather-related word on the board. Distribute three dry-erase markers to volunteers with ideas. Wind. Wind is the movement of air caused by the uneven heating of the Earth by the sun.


It does not have much substance—you cannot see it or hold it—but you can feel its force. It can dry your clothes in summer and chill you to the bone in winter. It is strong enough to carry sailing ships across the ocean and rip huge trees from the ground. It is the great equalizer of the atmosphere, transporting heat, moisture, pollutants, and dust great distances around the globe. Landforms, processes, and impacts of wind are called Aeolian landforms, processes, and impacts. Differences in atmospheric pressure generate winds.

The boundary between these two areas is called a front. Prevailing winds are winds that blow from a single direction over a specific area of the Earth. The Coriolis effect causes some winds to travel along the edges of the high-pressure and low-pressure systems. Wind Zones Polar EasterliesPolar easterlies are dry, cold prevailing winds that blow from the east. Results of Wind. Sandy's Hook: How Unusual Is This?

Sandy's Hook: How Unusual Is This?

Typically by late October, hurricanes forming in the central or western Atlantic Ocean have a good chance of "recurving", or being caught up in the polar jet stream, and turning away from the U.S. mainland. Those forming in the western Caribbean have a better chance of hitting the U.S. in late October, particularly Florida, as we saw 7 years ago with Hurricane Wilma.

National Maps. NOAA Education Resources Website. Weather Questions and Answers. What are cold fronts and warm fronts? Fronts are the boundaries between air masses of different temperature.

What are cold fronts and warm fronts?

If warm air is moving toward cold air, it is a “warm front”. These are shown on weather maps as a red line with scallops on it. If cold air is moving toward warm air, then it is a “cold front”. Cold fronts are always shown as a blue line with arrow points on it. If neither air mass is moving very much, it is called a “stationary front”, shown as an alternating red and blue line. Usually, a cold front will be associated with a warm front, with a low pressure center, connecting them (see above).

Most of Earth's disturbed weather (widespread cloud and precipitation systems) outside of the deep tropics occurs along or near fronts as part of extratropical cyclone systems.
