Down to Earth Surface conditions of the planets Venus and Mars are compared with those of Earth, and scenes of Earth's living landscapes lead into a discussion of how unique Earth truly is. Major topics addressed in the series, including plate tectonics, natural resources, seismology, and erosion, are introduced in this program. However, this notion changed dramatically over time, especially after the invention of the telescope.

How does rain form? Water droplets form from warm air. As the warm air rises in the sky it cools. Water vapor invisible water in the air always exists in our air. Warm air holds quite a bit of water. For example, in the summer it is usually very humid.

When enough of these droplets collect together, we see them as clouds. If the clouds are big enough and have enough water droplets, the droplets bang together and form even bigger drops. When the drops get heavy, they fall because of gravity, and you see and feel rain. When clouds develop or rain occurs, something is making the air rise.

Several things can make this happen. Mountains, low-pressure areas, cold fronts, and even the jet stream. How big are raindrops? Raindrops are much smaller than we think!

They are actually smaller than a centimeter. How fast do raindrops fall? Not including wind-driven rain, raindrops fall between 7 and 18 miles per hour 3 and 8 meters per second in still air.

The range in speed depends on the the size of the raindrop. Air friction breaks up raindrops when they exceed 18 miles per hour. What is a flood?

What is a flash flood? A flash flood is sudden flooding that occurs when floodwaters rise rapidly with no warning within several hours of an intense rain. They often occur after intense rainfall from slow moving thunderstorms.

In narrow canyons and valleys, floodwaters flow faster than on flatter ground and can be quite destructive. Do flash floods hurt people? Flash floods are the 1 weather-related killer in the U. Know beforehand if your area is a flood risk.

How much water is needed for your car to float away? A mere 2 feet of water can float a large vehicle or even a bus. This is why you should never drive through flooded roads.

Just 6 inches of rapidly moving flood water can knock a person down. What is a monsoon? A monsoon is a seasonal wind, found especially in Asia that reverses direction between summer and winter and often brings heavy rains.

In the summer, a high pressure area lies over the Indian Ocean while a low exists over the Asian continent. The air masses move from the high pressure over the ocean to the low over the continent, bringing moisture-laden air to south Asia.

During winter, the process is reversed and a low sits over the Indian Ocean while a high lies over the Tibetan plateau so air flows down the Himalaya and south to the ocean.SURREY has been rocked by a magnitude earthquake today - the second in just 12 hours.

The quake was the sixth to shake the area near both Gatwick and Heathrow airports in just four weeks - and. Jul 17,  · 2/10 - Missouri's Governor convened a panel of officials in New Madrid who are on the front line of emergency response.

From AP. Missouri state geologist Joe Gillman said an earthquake the magnitude of the quakes is expected to happen just once every years. Final Installment: Earthquakes Tectonic plates have a lot of _____. There is constant pressure on them, but it takes a whole lot of energy to It is actually by studying these seismic waves that we figured Microsoft Word - final earthquakes gap notes sci docx.

A M w earthquake occurred in Christchurch on 22 February at p.m. local time ( 21 February UTC). The earthquake struck the Canterbury Region in New Zealand's South Island and was centred 2 kilometres ( mi) west of the port town of Lyttelton, and 10 kilometres (6 mi) south-east of the centre of Christchurch, at the time New Zealand's second-most populous city.

Seismology (/ s aɪ z ˈ m ɒ l ə dʒ i /; from Ancient Greek σεισμός (seismós) meaning "earthquake" and -λογία (-logía) meaning "study of") is the scientific study of earthquakes and the propagation of elastic waves through the Earth or through other planet-like bodies.

multiple systems’ interconnections and feedbacks. In addition, Earth is part of a broader system—the solar system—which is itself a small part of one of the many galaxies in the universe.
