Chemistry [8.1]
What are the 3 subatomic particles that make an atom?
Proton, neutron and electron
What is a reactant?
What you put into a chemical reaction
What happens to kinetic energy when I increase the speed of an object?
It also increases
How do igneous rocks form?
Magma cooling below (intrusive) or above (extrusive) the earth's surface.
List three consequences of climate change.
Frost free growing season, changing precipitation patterns, droughts and heat waves, hurricanes, arctic ice, ocean acidification, flooding and sea level increase.
What is the difference between an atom and a molecule?
A molecule is made of more than one atom bonded together
What percent of the energy moves up each step of an energy pyramid?
10%
What is the difference between kinetic energy and potential energy?
Kinetic is energy of movement and potential is stored energy
What is one of the processes that deposited copper in Utah?
Magma from mantle, groundwater, tectonic plates breaking crust, sedimentary rock layers, etc...
Are digital or analog signals more reliable for storing data?
digital
What does it mean if we say a material is synthetic?
It is not found in nature, created by man.
List 3 different places we find carbon.
Oceans, animals, plants, rocks, air, fossil fuels, etc...
What is transferred by a wave?
Energy NOT matter
When magma pushes up through the crust, it can go straight up or sideways or form a big blob. Give the name of ONE of these formations.
Dikes, sills, igneous intrustions, and batholiths
What type of wave are sound waves?
Longitudinal/compression
List 3 things that indicate a chemical reaction happened.
Production of a gas, color change, odor change, temperature change, formation of a new substance
What living things do not do respiration?
None of them!
How can I increase the energy of a wave?
Increase the amplitude (or frequency of a light wave)
Where are you most likely to find mineral deposits around the world?
Along plate boundary lines
What was the effect in Yellowstone when the wolves were taken out?
The ecosystem suffered because other animal populations grew too much because there were no natural predators.
What does it mean if a reaction is exothermic?
Produces heat - feels hot
What are the reactants for photosynthesis?
Carbon Dioxide and Water
Which type of wave does not require a medium to travel through?
Electromagnetic (light)
What is the difference between weather and climate?
Weather is the day-to-day/short-term.
Climate is long term weather/ average
What are the reactants for cellular respiration?
Glucose and Oxygen
