  1. wave animations animations 2

  2. A fault: • break in Earth’s crust/plate • found at a plate boundary • Stress causes the crust to break There are 3 types of faults….

  3. Faults

  4. NORMAL FAULT Plate above fault line drops. Stress=tension Boundary=divergent

  5. Divergent Boundary Where 2 plates are moving apart At oceanic crust= seafloor spreading Landforms at plate tectonic boundary: rift valley, also seafloor spreading

  6. Divergent Boundary If occurs at continental crust forms a rift valley

  7. STRIKE-SLIP FAULT Plates move past each other. Stress=shearing Boundary=transform

  8. Transform Boundary • where 2 plates are sliding past each other in opposite directions. • Land is neither created nor destroyed; just shifting. Landforms at boundary plate tectonic boundary: neither created or destroyed, but causes Earthquakes.

  9. REVERSE FAULT Plate above fault line rises up. Stress=compression Boundary=convergent

  10. Convergent Boundary = where 2 plates collide. • Possible results: 1. mountains 2. subduction- the most dense plate is pushed down Landforms at boundary plate tectonic boundary: mountain building, or subduction of most dense plate where volcanoes can form.

  11. Minerals

  12. Properties of minerals help determine their usefulness. Note: Minerals that contain useful metals or nonmetals are called ores.

  13. Chemical Properties: 1. Ability to burn- can it be burned to provide heat or energy (fossil fuels)? 2. Reacts to Acids- if mixed with an acid…is there fizzing or release of gases? Physical Properties: 1. Hardness- how soft or hard a mineral is. Uses Mohs’ Hardness Scale for rating. Talc=softest Diamond=hardest Remember the Lab: we scratched mineral on glass 2. Luster- how light is reflected from mineral’s surface. 3. Color- observable color of mineral 4. Streak- the color made when mineral is scratched on a tile. 5. Cleavage/Fracture- how a mineral breaks apart or splits. 6. Density- the amount of mass in a given space. Mass found by using Triple Beam Balance

  14. Astronomy

  15. spring winter summer fall

  16. Crescent Moon 1st Quarter Waxing Gibbous New Moon Full Moon 3rd Quarter Wanning Gibbous Wanning Crescent

  17. A. Refracting Telescope- Convex lenses gather light and focus it in a small area. Used by Galileo in 1609. Types of Optical Telescopes

  18. B. Reflecting Telescope – Light enters the end and reflects on mirrors. Make observations through eyepiece. Used by Isaac Newton 1668 Types of OpticalTelescopes

  19. 2. Radio Telescopes- Receives radio waves from objects in space. Can be used in all weather and at all times of day Telescopes Video

  20. Large buildings that store large optical telescopes Observatories

  21. orbit around Earth collect information while in space Not affected by Earth’s atmosphere Satellites Natural satellite examples: 1. Moon orbiting Earth 2. Planets orbiting the Sun.

  22. Travel out of Earth’s orbit to collect info instruments are based on the goals of the “mission” Space Probes Mariner 10 Giotto Luna

  23. Our solar system formed from a swirling cloud of gas and dust. The sun -made from the densest matter that became very hot and started to produce its energy by nuclear fusion. Astronomy Introduction

  24. The remaining matter continued swirling around the sun because of the sun’s gravity and eventually clumped together to make solid forms =planets, moons, and other objects of space. Introduction

  25. In order from the sun- Mercury; Venus; Earth; Mars (inner) Jupiter; Saturn; Uranus; Neptune (outer) The Planets Weak gravitational pull due to smaller mass Stronger gravitational pull due to larger mass ROCKY GASEOUS

  26. Larger chunks of rock Vary in size and shape In Asteroid Belt between Mars and Jupiter Revolve around sun in 3-6 years Asteroids-

  27. Meteoroids- smaller chunks of rock and dust in space. 1. randomly move about space ; no specific orbit 2. come from remains of comets and asteroids • Meteor- a meteoroid that burns in the atmosphere- produces a streak of light. • nickname: “Shooting star” • MeteoriTe- a meteoroid that doesn’t burn up in the Earth’s atmosphere. It Touches Earth.

  28. Meteors Meteors Meteroids MeteoriTe
