Steering wheel does not return to center after corner, what is the issue?: A.) binding bearing in steering column B.) loose power steering belt - Binding bearing in the steering column = this would prevent steering wheel from returning to center. Steering wheel shudders while turning, what could be the cause? (Vibrating) A.) air in power steering fluid B.) loose power steering belt - Both= air in power steering fluid would cause cavitation and loss of hydraulic assistance / a slipping and...

How Old are the oceans - 4 billion years How were atmospheres and oceans formed - outgassing and icy commets what is outgassing - when volcanoes erupt and water vapor is condensed and turned into clouds and rain What are the internal Layers of earth - lithosphere asthenosphere mesosphere outer core inner core Lithosphere - Crust and Upper Mantle Asthenosphere - upper mantle (below lithosphere) Mesosphere - Rest of Mantle Outer core and inner core - outer fluid inner so...

origin of earth - • Supernova: death of a star (great explosion) • Supernova happened 4.6 bya, dust and gas flattens to a disk and spins faster due to gravity and solar nebula formed. • Solar Nebula: describes formation of Earth 4.5 bya • Nebula: gas cloud origin of oceans - • volcanic explosion, H2O condensed and rained down for thousands of years to create oceans • icy comets hitting earth (responsible for 1/2 of earths ocean water) origin of life - • 4.5 bya ...

Biological Productivity - the rate of generation of biomass in an ecosystem; western margins of continents have high prosuctivity and the Artic has the most because of high levels of upwelling and downwelling bc there is no thermocline Photosynthesis formula - 6CO2 + 6H2O + sunlight ---> C6 H12 O6 + 6O2 Photosynthesis - Inputs: Carbon Dioxide, water, sunlightOutputs: Glucose, oxygen Euphotic Zone - Upper layer of a body of water through which sunlight can penetrate and support photos...

How was the solar system formed? - -a supernova (explosion of a start when it runs out of fuel) -4.6 billion years ago how was the earth formed? - -a nebula made of gas and dust -was formed 4.5 billion years ago how did oceans form? - -A volcanic expulsion - rained for thousands of years -hit by an icy comets -volcanic out gassing and ice from comets when did life form? - -3.7 billion years ago how long have animals been around for? - -600 million years ago how long has pho...

What is the origin of the Earth? - Formed out of a solar nebula What are the origins of Life? - Archaea - the oldest origin of life on Earth What is kinetic energy? - The energy of motion What is heat energy? - Energy created by particles of matter rubbing together What is density? - A measurement of the amount of matter in a given volume of something. (mass per unit volume) What is convection? - Transfer of heat through currents caused by difference in temperature, which cause di...

Euphotic zone - first 200 meters -where photosynthesis can take place -suns radiation can be absorbed Seed Plants - -true plants -not very abundant -grasses, eelgrass and surfgrass -mangroves -like warm, muddy waters -have a root system Protists - a) large algae(seaweed) -brown algae(kelp), green (sponge weed), red (rhodophyta) b) phytoplankton(small algae) -most producers -diatoms -coccolithophores -dinoflagellates Eukaryotes - seed plants and protists Prokaryotes - -an...

How does heat affect density? - Hot water expands Which layer composes the plates? - Lithosphere In which tectonic setting(s) do trenches form? - Convergent, ocean-ocean, ocean-cont. What characteristic or process drives plate motions? - Sea Floor Spreading In what direction is the Pacific Plate moving relative to the North American plate? * - North West At what rate does seafloor spreading occur? - 2-5 cm per year Which tectonic features form the deepest locations in the ocean...

The Water molecule and basic atomic structure? - 2 positive end hydrogen and one negative end oxygen what makes up the water molecule, the charges, the bond angle? - H end- positive charge O end- negative charge looks like a mickey mouse head What's so peculiar about this molecule? - The fact that is has hydrogen bonds which are independent of the covalent bonds as well as it being a polar molcule H- The kinds of bonds in the water molecule? The kinds of bonds connecting all the wa...
