What should scientists consider when studying tree rings to understand the variations in the local climate?
What should scientists consider when studying tree rings to understand the variations in the local climate? The change in Earth’s tilt and its orbit around the Sun cause climate change. The increase of sunspots increases Earth’s temperature. The movement of continents changes wind patterns and ocean currents.
How do tree rings show climate change?
The color and width of tree rings can provide snapshots of past climate conditions. For example, tree rings usually grow wider in warm, wet years and they are thinner in years when it is cold and dry. If the tree has experienced stressful conditions, such as a drought, the tree might hardly grow at all in those years.
What type of climate do trees produce wider rings?
Tree rings usually grow wider in warm, wet climates and are thinner in climates where it is cold and dry.
What should scientists consider when studying tree rings to understand the variations in the local climate patterns in their width their density and their composition?
Answer: The color and width of tree rings can provide snapshots of past climate conditions. Because trees are sensitive to local climate conditions, such as rain and temperature, they give scientists some information about that area’s local climate in the past.
What can you determine about the climate during the 15 year period?
What can you determine about the climate during the 15-year period during which the tree rings grew wider? The climate was warmer and wetter. The climate was warmer and drier. The climate was colder and wetter.
What most likely caused the ice age?
What causes ice-ages? Fluctuations in the amount of insolation (incoming solar radiation) are the most likely cause of large-scale changes in Earth’s climate during the Quaternary. In other words, variations in the intensity and timing of heat from the sun are the most likely cause of the glacial/interglacial cycles.
What is the opposite of an ice age?
Yes, and there was such a period about 55 million years ago called the Paleocene-Eocene Thermal Maximum, in which global average temperatures rose to about 7-8° C warmer than they were a just 20000 years prior (which was similar to today).
