Problem: Process: - The organism must die to begin the process - The soft tissue decomposes - The bones are left behind - Scavengers tear the body apart and move the bones elsewhere - Wind and rain also scatter the bones further - The bones left behind will weather and become buried by sand and soil - The proteins in the bone are replaced with minerals that are dissolved in the soil - This creates a rock-like substance called a fossil - Water and wind erosion wear away the layers of soil on top of the fossil - This makes discovery of the fossil possible. Question: suppose there was an asteroid strike happens, how will it affect there will not be as many fossils. - A: more - B: less - C: no effect

A: B

Problem: Process: - The air is cold - Water is in the air - The water forms tiny ice crystals - The ice crystals collide with each other - The ice crystals stick to each other - The ice crystals get bigger as more of them stick together - The ice crystals get too heavy to be in the air - The ice crystals become snowflakes - The snow flakes fall to the ground as snow. Question: suppose there is less cloud cover happens, how will it affect The snow becomes less. - A: more - B: less - C: no effect

A: B

Problem: Process: - You inhale - The air enters the mouth and nose - The diaphragm contracts - Air fills all the sacks in the lungs - Oxygen passes through the sacks into capillaries - The blood is passed to the blood in the capillaries - The blood carries the oxygen to the heart - The heart pumps the oxygenated blood to the body. Question: suppose the lung is not healthy happens, how will it affect there is nose to inhale. - A: more - B: less - C: no effect

A: A

Problem: Process: - Wind passes the turbines and moves the blades - The shaft of the turbine spins - Shaft is connected to a generator - The generator uses the spins of the shaft to rotate a rotor - The rotor spins inside the core, which has magnets inside surrounded by wire loops inside - The spinning of the rotor in the core generates electricity - Question: suppose prizes are awarded for winners happens, how will it affect LESS electricity being generated. - A: more - B: less - C: no effect

A:
C
