Flow Map: Gravity Gravity Core •Gravity makes the Earth round •Without gravity we would float to space •Gravity keeps astronauts from floating away in space Moon •The core is split into 2, the outer core and inner core •The inner core is 51506370km below Earth's surface. •The inner core mainly consists iron, nickel, sulphur, carbon, oxygen, silcon and potassium. •The inner core is 5,0006,000c •The outer core is 28905150km below earth's surface. •The outer core is mainly liquid and consists iron, some nickel, 10% sulphur and oxygen •The outer core is about 4000-5000c •When the Earth rotates, the outer core spins around which creates Earth's magnetism •The Earth spins around the sun like the moon spins around Earth •Earth keeps the moon in place •The Moon takes 27.3 days to orbit earth but because Earth is spinning it takes 29.5 days •The moon has 1 6th of Earth's gravity Flow Map: Atmosphere . Atmosphere • The atmosphere is divided into 5 layers. • The troposphere, stratosphere, mesosphere, thermosphere and exosphere. Troposphere, Stratosphere and Mesosphere! • The first layer is the troposphere that is half of Earth's atmosphere. • The troposphere is known to make the weather • The stratosphere is a very stable layer and thats where aircrafts fly. • The stratosphere has a ozone layer that absorbs harmful rays from the sun • The mesosphere is where the meteors or rock disintigrate from fire Thermosphere and exosphere • The thermosphere is where the auroras are and where space shuttles orbit. • The exosphere is extremely thin and is the upper layer of our atmosphere Flow Map: Temperature Average and hottest • The average temperature is 15 Degrees celcius • The hottest place is the lut desert in Iran the temperature is 70.7 degrees celcius Percentage of oxygen • Our air is mainly nitrogen and carbon dioxide • Only 5% is oxygen Pollution • In Bejing and Hong Kong there have been sightings of mutations like when a lady spotted a one armed snake • Bejing creates the same pollution as 300 suburbs in Australia
