5 Written Questions

1. chunks of rock or dust from space
2. English mathematician and scientist who invented differential calculus and formulated the theory of universal gravitation, a theory about the nature of light, and three laws of motion. His treatise on gravitation, presented in Principia Mathematica (1687), was supposedly inspired by the sight of a falling apple.
3. large clumps of ice, dust and frozen gases that travel around the Sun in long elliptical orbits
4. A loop of gas that protrudes from the sun's surface, linking parts of sunspot regions
5. Polish astronomer who produced a workable model of the solar system with the sun in the center (1473-1543)

1. a a gaseous layer of the sun's atmosphere (extending from the photosphere to the corona) that is visible during a total eclipse of the sun
2. b This astronomer stated that the orbits of planets around the sun were elliptical, the planets do not orbit at a constant speed, and that an orbit is related to its distance from the sun
3. c continuous stream of high-energy particles released into space in all direction from the sun's corona
4. d the process by which hydrogen atoms join together to form helium, releasing energy
5. e elongated, closed curve that describes Earth's yearlong orbit around the Sun

3. An ancient Greek astronomer who proposed a way of calculating the movements of the planets on the assumption that they, along with the sun and the stars, were embedded in clear spheres that revolved around the Earth. His beliefs prevailed for nearly fifteen hundred years, until the modern model of the solar system, with the sun at the center, was developed from the ideas of Copernicus.

5 True/False Questions

1. Asteroid → rocky metallic objects that orbit the sun but are too small to be considered planets found mainly between Mars and Jupiter

   True        False

2. Heliocentric System → A description of the solar system in which all planets, stars, and moons revolve around earth. The Ancient Greeks believed we are in a celestial sphere and everything is perfect and un changeable.

   True        False

3. Corona → the outermost region of the sun's atmosphere that you see during an eclipse

   True        False

4. Galileo → Italian astronomer and mathematician who was the first to use a telescope to study the stars; demonstrated that different weights descend at the same rate; perfected the refracting telescope that enabled him to make many discoveries (1564-1642)

   True        False

5. Geocentric System → A description of the solar system in which all planets, stars, and moons revolve around earth. The Ancient Greeks believed we are in a celestial sphere and everything is perfect and un changeable.
