Which of the following do not provide evidence that a meteor strike was a partial cause of the Cretaceous-Paleogene mass extinction? a. A potential meteor crater off the coast of Mexico b. High layers of iridium in soil deposits in the geologic record at that time c. Shocked quartz was formed in large quantities at that time around the potential impact site d. An ozone hole appeared in the atmosphere at the time of the meteor strike
Scientists are examining the possible role of a large asteroid in the cretaceous mass extinction event. A large asteroid strike would likely have caused rapid climate cooling and the diffusion of sunlight. which of the following statements are the best null and alternative hypotheses when scientists look at the geologic evidence of extinction related to the asteroid strike?
Scientists are examining the possible role of a large asteroid in the Cretaceous mass extinction event. A large asteroid strike would likely have caused rapid climate cooling and diffusion of sunlight. Which of the following statements are the best null and alternative hypotheses when scientists look at the geologic evidence of extinction related to the asteroid strike? Null: The rate of extinction would be steady over the entire length of time the climate was altered. Alternative: The rate of extinction would be greatest immediately before the asteroid strike. Null: The rate of extinction would gradually decrease over the entire length of time the climate was altered. Alternative: The rate of extinction would be at its lowest immediately after the asteroid strike. Null: The rate of extinction would be steady over the entire length of time the climate was altered. Alternative: The rate of extinction would be greatest immediately after the asteroid strike. Null: The rate of…

List five pieces of evidence that support continental drift.
Which of the following are useful for reconstructing ancient environments? Group of answer choices A: the ice layers found in glaciers B: Oxygen isotope analysis C: Cores taken from ocean sediments D: fossil remains of plants and animals E: All of these answers are true
The theory of plate tectonics explains how Earth's continents move. According to this theory, which of the following statements is FALSE? A. Earth's crust is composed of relatively thin, light plates that float atop the dense, viscous upper layer of the mantle. B. Ocean basins can grow along divergent boundaries, where the ocean floor splits and spreads apart. C. Continental plates have relatively stable shapes because they are heavier than oceanic plates and tend to sink below oceanic plates where the two types meet. D. Many of Earth's mountains resulted from the collision of two continental plates along a convergent boundary.
The Permian extinction, which was the second most recent mass extinction, occurred about 251 million years ago. What is the leading hypothesis to explain the Permian extenction? An asteroid about 6 km in diameter collided with Earth, which vaporized the caribbean ocean, set fire to north and south America, and expelled enough dust into the atmosphere to block the sun enough to result in a winter like environment all across the globe for several years The Indian sub-continent collided with the Asian techtonic plate, giving rise to the Hymalayan mountains which altered the jet stream and caused the planet to enter an ice age Massive amounts of volcanic activity released tons of CO2, enough to significantly increase the temperature of the planet A new group of predators evolved that were significantly better at capturing prey, to the point that they drove many species (including other predators and eventually themselves) to extinction
Climatologists look for climate change in many components of the climate system. Which of the following statements has the least direct evidence? A. Global mean surface temperature has increased since 1850. B. Arctic sea ice, glaciers, and ice sheets have decreased in size over the past 50 years. C. The length of the growing season in the US has decreased since the 1890s. D. Global mean sea level has risen significantly since 1880.
