Q: Process: - The earth develops cracks deep beneath the surface - The cracks get very long and big in some places - The earth places pressure against the rocks on both sides of the cracks - The pressure causes the rocks to press against each other very hard - The cracks continue to develop - The earth moves against itself on both sides of the cracks - The pressure and movement around the cracks causes the rocks to crumble in some places - A lot of energy is released - The energy causes seismic waves - The seismic waves move the earth in an earthquake.  Question: suppose more pressure on rocks happens, how will it affect less seismic waves.  - A: more - B: less - C: no effect
A: B

Q: Process: - Greenhouse gases are released into the air by human activities - The earth changes energy from the sun into heat - Heat rises from the ground - Greenhouse gas molecules in the atmosphere prevent the heat from going into space - The temperature of the earth increases - The temperature continues to rise and melts the polar ice caps - The temperature rises even faster.  Question: suppose people try to conserve more resources happens, how will it affect greenhouse gases trap more heat.  - A: more - B: less - C: no effect
A: B

Q: Process: - People dig up coal from the ground - People burn coal for heat or electricity - Pollution from the coal goes into the sky - Coal pollution enters clouds - Clouds rain over an area - The polluted rain becomes acid rain.  Question: suppose people are not offered an alternate heat source happens, how will it affect less coal pollution enters clouds.  - A: more - B: less - C: no effect
A: B

Q: Process: - The nuclei of some atoms have too few or too many neutrons - The atoms become unstable - The atoms split - In alpha decay, two protons and two neutrons are released from the atom - In beta decay, a neutron changes into a proton and an electron - The proton joins the nucleus of the atom - The electron is released -   Question: suppose the atoms are less stable happens, how will it affect less protons are releases from the atom.  - A: more - B: less - C: no effect
A:
