- Q1Earth’s magnetic field protects us from:tsunamissolar flaresaurorassolar wind60s
- Q2What is an effect of lower levels of solar radiation hitting Earth?increased phytoplankton activitydecreased carbon dioxide levelsincreased incidences of skin cancerdecreased rates of photosynthesis60s
- Q3Which of these best describes Earth's hierarchy in space?Earth, solar system, local group, supercluster, universeEarth, solar system, galaxy, local group, supercluster, universeSun, Earth, solar system, local group, universeEarth, solar system, local group, galaxy, universe, supercluster60s
- Q4Theory that the universe began 13.7 billion years ago as a singularity that expanded is calledThe Theory of plate tectonicsthe Big Bang TheoryThe Theory of universal gravitation60s
- Q5Which statement describes Earth's motion around the sun?Speed increases the closer Earth is to the sun and decreases the farther it is from the sun.Speed increases the farther Earth is from the sun and decreases the closer it is to the sun.speed of Earth is constant regardless of its distance from the sun.The speed of Earth is constant because the distance remains the same between Earth and the sun.60s
- Q6Which statement is true?Earth rotates around the sun every 365 daysEarth revolves on its axis every 24 hoursEarth revolves on its axis and rotates around the sunEarth rotates on its axis and revolves around the sun60s
- Q7What causes Earth's seasons?the retrograde motion of Jupiterregularly timed solar flares from the sunThe tilt of Earth's axis as it revolves around the sunThe straight alignment of the sun, moon, and Earth60s
- Q8Why can it be winter for the northern hemisphere in December, but summer in the southern hemisphere?The northern hemisphere is tilted away from the sun in the winter and the southern hemisphere is tilted toward the sun, causing it to be summer in the southern hemisphereBecause the moon sometimes gets in the way of the sun and causes the northern hemisphere to cool downThe perihelion occurs in the Winter, causing the southern hemisphere to become warmerThe uneven heating of the Earth causes sunlight to be directed more towards the southern hemisphere in December60s
- Q9Which natural phenomenon occurs as a result of Earth rotating on its axis?seasonsmovement of tectonic platesday and nightdeep ocean currents60s
- Q10How does the tilt of Earth's axis affect the seasons?by deflecting the harmful rays of radiation emitted by the sunby influencing the rate of chemical reactions occurring in the atmosphereby changing the speed of the rotation of Earthby changing the amount of direct solar energy reaching the surface of Earth60s
- Q11How does heat from the sun get to Earth?by convection, using liquids and gases to transfer the heatby radiation, using electromagnetic waves to transfer the heatby conduction, using solids to transfer the heatby absorption, using primary waves to transfer the heat60s
- Q12Which describes the difference between nuclear fission and nuclear fusion?Nuclear fission splits a heavier nucleus into smaller nuclei, and nuclear fusion is the process that produces the radiant energy of stars.Nuclear fission produces energy in nuclear power plants, and nuclear fusion produces the energy in the core of Earth.Nuclear fission produces the energy in the core of Earth, and nuclear fusion produces energy in nuclear power plants.Nuclear fission is produced in stars, and nuclear fusion splits nuclei into smaller nuclei.60s
- Q13How does a straight alignment between Earth, the sun, and the moon impact the tides on Earth?It produces the least change in high and low tides.It produces the greatest change in high and low tidesIt produces diurnal tides.It produces semidiurnal tides.60s
