b. Not all planets rotate in the same direction. c. Revolution, not rotation, causes Earth’s days and nights. d. none of the above 15. Which of the following planets is NOT a gas giant?
3. The Sun appears bigger and brighter than all the other stars. This is because the Sun is the nearest star to Earth. 4. The Sun is the largest object in the Solar System.
Because its density is so high, neutrons spin in the same way that electrons do so must obey the Pauli Exclusion Principle. 6. A pulsar does not pulse, it emits beams of radiation that sweep around the sky as the neutron star rotates, and astronomers detect pulses when they sweep over the Earth. 11. Sometimes in binary systems, mass flows into a hot accretion disk around the neutron star and causes the emission of x rays.

Physical size = angular size x 2 x distance / 360 • Understand that constellations are groups of stars as seen from the Earth – the stars may not be close to each other at all • Our view of the celestial sphere is determined by where we stand on the Earth o Study the diagrams that show the path of stars as they rise and set and how those paths appear to differ depending on your location on the Earth • Know what causes the seasons (tilt of the Earth’s axis to it’s orbital plane) o Depend on how Earth’s axis affects the directness of sunlight o Sun’s altitude is also higher in Summer and Lower in Winter Summer solstice – highest path Winter solstice – lowest path Equinoxes – sun rises at exactly due east and sets exactly due west • Review the Moon’s phases • New Moon • Waxing (Right side of moon visible) o Waxing

Science Physics Core science questions and answers- Topic 1- The solar system- 1. What is a geocentric model? It is a model with the earth at the centre. 2. Describe two differences between ptolemy’s and Copernicus’s models- What is at the centre of the model and the way in which the planets followed smaller circles in their orbits in ptolemy’s model.
Unit 11 – AO1 – The Universe and the Big Bang Introduction - This AO explores the parts that make up the universe and how these parts tie in to each other to make up the world we live in. Check List - This assignment requires the following tasks to be completed: 1. Features of the Universe * The Universe * The Big Bang Theory * Stars * Galaxies * Constellations * Nebulae * Planets * Asteroids * The Sun 2. Life Cycle of a Star * Explain each of the 6 stages of a star’s life cycle. Include the name given to the star for each stage 3.
Introduction One look at the surface of the Moon should convince you that "empty space" is not so empty after all. There is actually a wide range of objects floating between the planets, from tiny particles to asteroids that can be a hundred miles across, debris left behind when the planets were formed. These objects can be perturbed from their orbits (by a close passage by a planet, a passing star, any number of things) and onto paths that cross ours -- or any other planet or moon. When
The most logical answer is A. When the earth was just starting to form a big astoride hit earth and a large amount of material flew off to form the moon. 3. Sunlight is created from_______ a. Sun light Bulbs b. Thomas Edison c. Yo Moma d. Energy from Nuclear Fusion i. D. Sunlight is the energy that is released when a nuclear reaction causes hydrogen to form in to helium 4.
