I have 28 PHYSICAL SCIENCE LESSONS AND 1 EXAM I need completed asap.

Natural Hazards” Please respond to the following:

• Access the “USGS Hazards” website under the Natural Hazards terms section of the Science Corner. You can also access the website at http://www.usgs.gov/natural_hazards/. Choose one (1) of the following geologic hazards: earthquake, landslide, or flood. Next, determine the key factors that influence the occurrence of your chosen hazard. Then, analyze the human role in elevating the risks of occurrence, as well as mitigation strategies to minimize damage and loss of life.
• Watch the video titled “Meet the Volcanoes” (2 min 57 sec) under the Volcanism terms section of the Science Corner. You can also view the video at http://www.pbs.org/wgbh/nova/earth/meet-volcanoes.html. Next, use the Internet or Strayer Library to research articles on the Mauna Loa Volcano in Hawaii and Mount Pinatubo in Philippines. Based on the type (i. e., cinder cone, shield, or composite) of volcano, and its common eruption characteristics, speculate on the societal and environmental damages that Mauna Loa and Mount Pinatubo would cause if they erupted today. Justify your response with evidence from your research.
• Describe three (3) ways that Wegener’s continental drift hypothesis has helped to shape modern plate tectonic theory, and then explain why his hypothesis was not widely accepted by his peers when first proposed. Next, analyze at least two (2) types of evidence used to support plate tectonic theory.

Discussion Question:

The Electromagnetic Spectrum” Please respond to the following:

• Watch the video titled “What Are Gamma Rays?” (1 min 39 sec) under the Gamma Rays terms section of the Science Corner. You can also view the video at https://www.youtube.com/watch?v=PPlrtgilgK8. Next, give your opinion on whether or not the benefits of space exploration to the Moon and Mars outweigh the risks and costs of exposing such travelers to gamma rays above Earth’s atmosphere. Provide a rationale for your response.
• Watch the video titled “Video Tour of the Electromagnetic Spectrum” (5 min 3 sec) under the EM Spectrum terms section of the Science Corner. You can also view the video at http://missionscience.nasa.gov/ems/emsVideo_01intro.html. Next, describe one to two (1-2) ways that you encounter and utilize electromagnetic radiation in your daily life. Note: Feel free to include both naturally occurring examples, as well as any man-made technologies.
• Choose a technology device that makes use of the EM Spectrum. Next, explain how this device works using terminology learned in this chapter.
