Discuss what is happening in a free body diagram
shows all the forces acting on an object
Asteroid
Large rock in space
Crust
made up of continental and continental, part of the lithosphere
Be able to discuss the difference between weather and climate
Weather is the day to day changes in the atmosphere. It is affected by air pressure, temperature, and humidity
Climate is the long term pattern of weather for a given area. It is affected by longitude, elevation, bodies of water, biosphere, and landscape.
Describe energy transformations happening in the world
kinetic to potential energy and vice versa
total energy the same throughout a system
Discuss the life cycle of a high and low mass star
Big stars use up fuel quickly so they don't shine for long but smaller stars use fuels slower so they shine longer.
Comet
Mostly ice has a tail
Mantle
lithosphere (part of the top of mantle)
asthenosphere
Mesosphere
Discuss the layers of the atmosphere and phenomena that occur within them
Troposphere - Weather
Stratosphere - Ozone layer
Mesosphere - Meteor burn up
Thermosphere - Ionosphere/northern lights
Exosphere - satellites
Describe the different plate boundaries and the landforms they create
convergent - plates collide making volcanoes and mountains
collision and subduction
divergent - plates move away from each other making new crust and trenches
transform - plates move horizontally by each other - makes earthquakes
Be able to describe the big bang and several ideas that support it
Big Bang- The beginning of space, time, and everything in it
Red and Blue shift of light
Cosmic Microwave Background Radiation
Abundance of Light Elements
Meteor
comet or asteroid that enters earth's atmosphere
Core
inner outer
Discuss the difference between AC and DC power
AC - alternate current in a circuit as housing
DC - direct current in a circuit such as batteries
Describe Newton’s laws and their presence in real-world examples
An object in motion will stay in motion and an object at rest will remain at rest unless acted upon by an outside unbalanced force.
F=ma
Every action force has a reaction force that is equal in magnitude and opposite in direction
Describe use and importance of relative and absolute dating.
relative dating
rock layers of sedimentary rock, older rock farther down and younger near the top of crust
Absolute dating - gives exact age of fossils by radioactive dating using isotopes
use of half lives of isotopes
Meteorite
Meteor that has made it to earth's surface
relative dating
rock layers of sedimentary rock, older rock farther down and younger near the top of crust
The interactions of magnetic poles and how magnetic field lines are drawn
north and south poles attract each other
magnetic field lines are drawn from north to south poles
Describe the difference between a Series and Parallel Circuit
Series has one path so current is the same in the circuit. Each additional resistor increases the resistance.
Parallel has multiple branches each with the same voltage as the battery. Each resistor added in parallel decreases the resistance.
the vocabulary words with magnetism: magnetic poles, magnetic domain and magnetic field
magnetic poles - region on a magnet that produces a magnetic force
magnetic domain - cluster of aligned atoms in a magnet
magnetic field - the space around the magnet that is producing the magnetic force
Meteoroid
Meteor that was reflected back to space
Absolute dating
gives exact age of fossils by radioactive dating using isotopes
use of half lives of isotopes
Describe the different types of waves (longitudinal and transverse) and how they are used in everyday life.
longitudinal vs transverse
EM waves vs Mechanical
examples - ocean and seismic waves, moving a slinky etc
How magnets work with a compass
Earth is a magnet -
geographic north is a south magnetic pole that attracts the north magnetic pole of compass
