Question

What are varves? Varvesw are annual layers of sediment laid down by glaciers as they melt each summer. Varves are annual layers of sediment laid down by stream floods dervied from glacial melting. Varves are tree rings that record temperature variability. They are laid down in locations where trees obtain as much moisture as they need. These trees grow in places like rainforests (both temperate and tropical), temperature. These temperature-dependent tree rings are called varves. Varves are annual layers deposited in lake basins, created by freezing over the lake in winter (creating very fine sediment) and thawing the lake in summer (creating deposits with larger sediment). What is eccentricity? Eccentricity describes the ""wobble"" that takes place as Earth revolves around the sun. This wobble changes the timing of perihelion and aphelion. Eccentricity describes how circular or how oval Earth's orbit is around the sun. All of the other answers are correct, and thus this is the best answer. Eccentricity describes the tilt of Earth's axis with respect to the plane of the ecliptic. The oxygen isotopes in shells of marine organisms tell physical geographers something about the past. What? The oxygen in the shells record the volume of ice that formed in the past. The oxygen in the shells record the temperature of the ice melting from Antarctica Oxygen isotopes are used to calculate the mass of water in different reservoirs of the hydrosphere, including glaciers. Oxygen isotopes record the temperature of the atmosphere above Antarctica, and hence record the glacial-interglacial fluctuations that have occurred. What is obliquity? All of the other answers are correct, and thus this is the best answer. Obliquity describes the ""wobble"" that takes place as Earth revolves around the sun. This wobble changes the timing of perihelion and aphelion." Obliquity describes the tilt of Earth's axis with respect to the plane of the ecliptic. Obliquity describes how circular or how oval Earth's orbit is around the sun. What change generated the period known as the Little Ice Ages? Earth's eccentricity changed just enough to decrease temperatures globally. Solar output decreased slightly during this period, leading to a colder period and the growth of glaciers. Earth's obliquity changed just enough to decrease temperatures globally. Earth's precession changed just enough to decrease temperatures globally.
