Chemistry
In the chemical formula, C6H12O6 how many elements are present? Name them.
3 = Carbon, Hydrogen, and Oxygen
What is Newton's First Law of Motion?
AN object at rest stays at rest and an object in motion stays in motion until an unbalanced force is applied.
What is an area where air pressure is lower than its surroundings resulting in turbulent, inclement weather?
Low-pressure system (L)
What is the main source of energy that fuels our weather and climate?
Solar energy
What adaptation is an instinctual action that increase an organism's chances of survival and reproductive success?
behavioral adaptation
How many atoms are present in the chemical reaction for Ca(OH)2 + H2SO4 --> CaSO4 + 2H2O?
12
Explain Newton's Third Law of Motion.
It states that when two objects interact, they exert forces on each other that are equal in size and opposite in direction. ACTION-REACTION
What are circular flows of material, generally liquids or gases, caused by temperature differences? (PSST - Hot goes UP, Cold goes DOWN)
Convection Currents
What is a cloud of gas and dust in outer space where stars are formed?
Stellar nebula
Which adaptation is a physical feature that increases an organism's chances of survival and reproductive success?
structural adaptation
What is the Law of Conservation of Mass?
Mass is neither created nor destroyed in a chemical reaction.
Which law is Force = Mass X Acceleration?
Newton's Second Law of Motion
This type of weather front does NOT progress, usually a cold front and a warm front meet!
Stationary Front
List and describe the 3 types of galaxies.
spiral - dense area of stars with 2 or more arms extended from it
elliptical - galaxy with rounded area of stars
irregular - a galaxy with no definite shape
What organelle is responsible for you looking like your parents?
nucleus
Name the evidence that there was a chemical change.
Production of gas, change in thermal energy, formation of a precipitate, and color change. (there can be a smell)
Four students built air-propelled rockets that were launched into the air. Which rocket had the greatest acceleration?
Rocket Mass Net Force
1 0.528 12.0
2 0.426 8.0
3 0.515 12.0
4 0.477 8.0
Rocket 3 23.3 m/s2
What are the prevailing winds that blow from the west to east between 300 and 600 north and south of the equator?
a) westerlies b)trade winds c)El Niño d)La Niña
a) westerlies
What type of tides are characterized with high high tides and low low tides during full and new moon phases, with the sun-earth-moon in a straight line?
Spring
Explain what a physiological adaptation is.
An internal process that increases an organism's chances of survival and reproductive success.
Explain the difference between a closed system and an open system in the Law of Conservation of Mass.
In a closed system, matter does not enter or leave so the mass will stay the same. In an open system, energy and matter are exchanged with the outside environment so mass may change.
Explain which and how Newton's laws are applied when kicking a soccer ball. (Look at teacher!)
1st Law = Ball sitting and Ball moving
2nd Law = Foot kicking the ball with force to move the ball faster
3rd Law = When the ball is kicked, the ball exerts the equal and opposite force to the player's foot
What is the term used for a large, rotating storm system with strong winds and low pressure center that forms over warm waters; the specific name for these storms that form in the Indian or South Pacific Ocean
Tropical Cyclone
What is the life cycle of an average sized star?
stellar nebula>average star>red giant>planetary nebula>white dwarf
Explain the ecological succession from the beginning to a climax community.
Natural event>rock>lichen & moss>soil>weeds & grasses>shrubs> trees> climax community
