4 Branches of Earth Systems Astronomy Meterology Geology Oceanography
What is the order of objects in the universe according to their size? Largest Smallest Universe Galaxy Solar System Star Planet (ex: Earth) Moon Comet Planets/moons may be reversed. However, this is a generally accepted hierarchy.
What is the galaxy we live in? Milky Way
How many stars are in our solar system? 1 (our sun)
What are the 3 main types of rock classification? Igneous Sedimentary Metamorphic
These (rocks) classifications are based on…… How they were formed Heat Pressure Cooling Weathering Erosion Compaction
How do rocks help explain the Earth’s history? Shows the changes in the Earth’s atmosphere/climate and different events that occurred on the Earth Fossil explain what creatures were present on the Earth Rock types showed that certain continents may have been together
3 layers of the Earth Outermost Inner Layer Crust Mantle Core
The 3 layers based upon….. Composition What they are made up of
5 layers of the Earth Outermost Innermost Lithosphere Asthenosphere Mesosphere Outer Core Inner Core
The 5 layers are based on their….. Physical characteristics
The outermost layer is broken into…. Tectonic Plates
3 types of plate boundaries Transform Divergent Convergent
What are the physical features formed at each boundary? Transform faults Divergent Ridges Convergent Trenches Mountains/Volc anoes
What are convection currents and what causes them? They are the rising of heated material and the sinking of cooled material. Caused by: Unequal heating from a heat source
3 examples of where convection currents can be found Asthenosphere Ocean/ water Air
What is the percentage of gases in the Earth’s atmosphere? Nitrogen 78% Oxygen 21 % Other about 1 % Helium, Hydrogen, Carbon Dioxide, & Argon
What causes the moon to appear in different phases throughout the month? Position of the Earth & sun
What causes the seasons? TILT of the Earth
Hurricanes vs. Tornadoes Hurricanes Size: Larger area covered Speed: Sustained: 74- over 155 mph Duration: over days Intensity: causes flooding & wind damage Intensity Scale: Saffir- Simpson Scale Tornadoes Size: smaller area Speed: Gusts: 65- over 200 mph Duration: usually minutes Intensity: hail & wind damage Intensity Scale: Enhanced Fujita Scale
