Mammatus Clouds Over Saskatchewan Explanation: Why is this cloud so bubbly? Normally, cloud bottoms are flat. The flatness is caused by moist warm air that rises and cools and so condenses into water droplets at a specific temperature, which usually corresponds to a very specific height. As waterdroplets grow, an opaque cloud forms. Under some conditions, however, cloud pockets can develop that contain large droplets of water or ice that fall into clear air as they evaporate. Such pockets may occur in turbulent air near athunderstorm. Resulting mammatus clouds can appear especially dramaticif sunlit from the side.

Scale Scale Description 4 Through independent work beyond what was taught in class, students could (examples include, but are not limited to): research current and past earth and sun conditions. investigate causes and possible solutions for global climate change. compare and contrast the patterns in the organization and distribution of matter in the sun, earth, moon system. compare and contrast different solar events and their impact on earth. 3 understand how the motions of the sun, stars and planets as observed from Earth relate to the motions of the Earth and other planets in space. understand how the movement and position of Earth influences life on Earth. be able to differentiate between astronomy and astrology. 2 determine the meaning of symbols, key terms, and other astronomy specific words and phrases relating to the Earth, Sun and Moon illustrate the patterns of distribution of matter in the sun, earth, moon system. list the physical properties of the Earth, Sun and Moon. describe the key parts of the Earth, Sun and Moon System 1 show the patterns of distribution of matter in the sun, earth, moon system. select from a list the physical properties of the sun, earth and moon. list the key parts of the structure of earth, sun and moon.

Formation of the Moon

 The Moon is mostly made up of the same elements that our crust and upper mantle are made of

 Video of the moon forming is on the website

This image shows a simple crater on Mars that has no central peak or terraces around its edges. The crater is 2 kilometers (about 1 mile) wide. An extensive blanket of ejecta covers the area around the rim. Image from the Mars Global Surveyor Copernicus is a large crater (93 kilometers or 60 miles wide) on the Moon. The inner walls of the crater have collapsed to form a series of step-like terraces, and a central peak is visible in the center of the image. Apollo 17 image courtesy of NASA. Simple craters are small bowl-shaped, smooth-walled craters (the maximum size limit depends on the planet). Complex craters are large craters with complicated features. Larger craters can have terraces, central peaks, and multiple rings.

Floor – The bottom of a crater, either bowl-shaped or flat, usually below the level of the surrounding ground. Central peaks – Peaks formed in the central area of the floor of a large crater. For larger craters (typically a few tens of kilometers in diameter) the excavated crater becomes so great that it collapses on itself. Collapse of the material back into the crater pushes up the mound that forms the central peak. At the same time, the rock beneath the crater rebounds, or bounces back up to add to the peak. Walls – The interior sides of a crater, usually steep. They may have giant stair-like terraces that are created by slumping of the walls due to gravity. Rim – The edge of the crater. It is elevated above the surrounding terrain because it is composed of material pushed up at the edge during excavation. Ejecta – Rock material thrown out of the crater area during an impact event. It is distributed outward from the crater's rim onto the planet's surface as debris. It can be loose materials or a blanket of debris surrounding the crater, thinning at the outermost regions. Rays – Bright streaks extending away from the crater sometimes for great distances, composed of ejecta material.

Impact basins are very large impact structures that are more than 300 kilometers (185 miles) in diameter. The largest impact basin on the Moon is 2500 kilometers (1550 miles) in diameter and more than 12 kilometers (7 miles) deep. Large impact basins are also found on other planets, including Mars and Mercury. The large circular dark areas in the image are impact basins, created as huge impactors struck the Moon. Lava later flowed across the low floors of the basins, giving them a darker, smoother appearance than the surrounding, brighter highlands. The dark basins can be seen by the naked eye.

 Set up Today!

 You need to read the front and back so that you know what you and your lab group are doing tomorrow!  If you don’t pre-read, you wont have time tomorrow  I wont grade anything unless you can explain what the procedure is for tomorrow.  You cannot start the lab tomorrow unless you have the pre-lab questions completed.  In your science journal  So start already!  If you don’t start on time, you might have to come in before or after school to complete it.  wompwomp
