Exam 1 (SCI 225) The majority of transform boundaries are found - correct answer Along mid-ocean ridges How did paleomagnetism provide evidence to support theory of plate tectonics? - correct answer Paleomagnetism demonstrated that rocks at the same distance from the mid-ocean ridge recorded the Earth's magnetic field's sense direction. What do weather and climate have in common? - correct answer They are both describing atmospheric conditions. Earth's atmosphere is best described as - correct answer 100 km thick 0.04% CO2 Would the Earth have seasons if the axis was vertical? - correct answer No. Seasons occur because of the tilt of Earth's axis and how this impacts the amount of direct and indirect sunlight. Why does direct and indirect sunlight matter? - correct answer Direct sunlight provides heat energy that warms the Earth's surface, while indirect sunlight, helps to distribute this heat more evenly across different regions of the planet. Explain THREE of the core aspects of Nature of Science as written about by McComas. Be able to relate each example to a concept or activity completed in class. - correct answer 1) Science demands and relies on empirical evidence. - The theory of continental drift needed evidence to support the movement of the continents across the Earth's surface. 2) There is no single step-by-step scientific method by which all science is done. - Alfred Wegner published three books about the origins of the continents, adding more evidence each time. 3) Scientific knowledge is tentative but durable. - The theory of continental drift paved the way for plate tectonics. 4) Science is a highly creative endeavor.
