Bell Work: Using your text, page 234, find the following answers for your bell work: 1. Unlike the earth, on the second planet from the sun (_________) the sun rises in the _____________ and sets in the __________. 2. Venus’ day and year are ________. 3. What is rotation? Revolution? Bell Work • Pick up a benchmark test from the front student desk. You will check your answers to the ones on the board. Any question you answered incorrectly, you will write on a separate piece of paper the question and then the appropriate answer and why that answer is correct. Today we will only do five. 6. C 7.

A VENUS • Second planet from the sun •Rotates in the opposite direction than earth •Venus has no moons •Is the hottest planet Earth’s Twin? • In many ways, Venus is like Earth’s twin. • They have about the same size, mass, and density. • BUT…Venus rotates in a different direction so… the sun rises in the west and sets in the east. (Retrograde rotation) http://www.cosmos4kids.com/extras/dtop_solsyst/venus_580.jpg Venus • Has the most dense atmosphere than any of the terrestrial planets • Mainly consists of carbon dioxide but also some deadly acids • The carbon dioxide traps thermal energy causing a greenhouse effect-causing the temperature to be so high • Average temperature 464*C • Venus has the hottest surface of any other planet in the solar system!

We can't see the surface of the planet because it has a very thick atmosphere filled with clouds that strongly reflect sunlight. • Nonetheless, space missions sent to Venus have managed to land on and photograph the surface while the Magellan spacecraft mapped the surface of the planet from above. • These maps reveal a surface covered with craters, over 1600 major volcanoes, mountains, large highland terrains, and vast lava plains.
