The Epic EARTH
Transcript: Diameter & Mass Gravitational Pull The Earth's axis is tilted 23.5 degrees away from the ecliptic Rotation Direction & Revolution Times Bibliography Life Forms Existence of Magnetic Field What Earth is Made of? The Earth's mantle is made up of silicon,iron,magnesium,aluminum,oxygen, and other minerals The Earth's crust is made up of mostly the same things but with potassium and calcium The Earth's core is extremely hot and is composed of nickel and iron The rotation direction of the Earth passes through the North and South poles of the planet. The time it takes for the Earth to make a full revolution is approximately 365 days Humans ... DUHHH Unfortunately, Earth has no rings at all Earth's atmosphere is a mixture of nitrogen, oxygen, and other gases that surround the Earth The Earth's atmosphere keeps us from being peppered by meteorites, basically a screen against deadly radiation The atmosphere has 5 major layers Troposphere: layer that provides most of our weather Stratosphere: ozone layer, blocks most of the suns harmful ultraviolet rays Mesosphere: meteors generally burn up in this layer Ionosphere: the ions in this layer create an electrical layer that reflects radio waves, allowing radio waves messages to be sent across oceans in the days before communication satellites Exosphere: solar systems compress this layer Earth's Distance From the Sun The Earth's magnetic field is 3.5 billion years old The magnetic field purpose is to protect the Earth's atmosphere from the solar wind. The Epic EARTH www.wired.com science.nationalgeographic.com www.windows2universe.org www.nasa.org www.universetoday.com Axis and tilt humans,trees,animals,flowers etc. all of these things are living and they live on Earth. The highest temperature recorded on Earth was 136 degrees located in the Libyan desert The coldest temperature recorded on Earth 126 degrees located in Antartica. Earth's Moons Earth has one moon and that moon goes through phases as a result in the moons rotation. The Earth's moon goes through 8 phases and the reason we can see the moon is because it reflects light from the sun Earth's distance from the sun is about 92,900,000 miles (149,500,000 km) Earth is third planet away from the sun The Earth's diameter is 7,918 miles (12,742 km) The Earth's gravitational pull is 9.807 m/s2 Eric Rose, Deanna Squires, Chassidy Khamninh, Christina Goodwin Range of Temperatures on Earth Rings? or Not Construction?
