2 Volcanoes 1.Magma reaches the surface and becomes lava. 2.Areas where the earth’s shifting plates meet or split apart 3.Lava, ash, and debris flows Challenge: Seismographs, tiltmeters, geodimeters, correlation spectrometers Slide 2

3 Western Diamondback Rattlesnake 1.Southwestern United States 2.Small rodents, rabbits, and birds 3.Around 60 inches long Challenge: None, they have live births Slide 3

4 The Butterfly Zone 1.Yellow cassia 2.No 3.By smell Challenge: Egg, caterpillar, chrysalis, butterfly Slide 4

5 Nova Online / Avalanche! 1.Snow-covered slope and a trigger 2.1 million 3.Avalanches Challenge: Answers will vary Slide 5

6 Spiders 1.Scorpions, ticks, mites, daddy longlegs 2.36,000 species 3.Giant bird-eating spider Challenge: Arachnologist Slide 6

7 Windows to the Universe 1.870,000 miles or 1,392,000 kilometers 2.88 Earth days 3.Atmospheric scientist Challenge: Nucleus Slide 7

8 Meteorology Program: Cloud Boutique 1.Cloud’s base above 18,000 feet 2.Cumulonimbus 3.Lenticular clouds are formed from strong wind flow over rugged terrain. Challenge: By their altitude, appearance, and origin Slide 8

9 Sea World: Coral Reefs 1.Great Barrier Reef, which stretches more than 1,240 miles 2.The sun 3.Fringing reef, barrier reef, and atoll Challenge: When forests are cut down, topsoil washes into rivers and into the sea. The soil smothers coral polyps and blocks sunlight, which corals need to survive. Slide 9

10 EduGreen 1.The effect caused when gases such as carbon dioxide, methane, and nitrous oxide trap solar radiation from escaping the atmosphere, keeping the Earth warm 2.Water molecules mixed with dust and smoke particles, forming a dense fog 3.Municipal waste, hazardous waste, and infectious waste Challenge: Answers will vary Slide 10

11 The World’s Biomes 1.Freshwater and marine 2.1/5 of the Earth’s surface 3.The Arctic tundra encircles the north pole and extends south to coniferous forests of the taiga. The Alpine tundra is found on mountains at high altitudes where trees can’t grow. Challenge: Water is a major natural resource, and is the basis of life. Slide 11

12 The Owl Pages 1.Parliament 2.1 to 13 (average is around 3 or 4) 3.Antarctica Challenge: They hunt other animals for food. Slide 12

14 Hurricane Hunters 1.Air Force 2.Four, if they have enough fuel 3.Hurricane Grace Challenge: Keesler Air Force Base in Biloxi, Mississippi Slide 14

15 Your Weight on Other Worlds 1.The amount of matter an object contains 2.Weight is the measure of the force of attraction or pull of gravity between two objects (such as you and the Earth.) 3.The force of gravity gets weaker with distance. It decreases with the square of the distance. Challenge: Answers will vary. Slide 15

16 Adventures of Herman the Earthworm 1.Through early European settlers who brought plants to North America in the 1600s and 1700s. Earthworms were hidden in the soil among the plants’ roots. 2.5 3.Gizzard Challenge: Oligochaeti Slide 16
