Which sources do scientists use to study ancient climates quizlet?

List three sources of information scientists use to learn about ancient climates. Tree Rings, Ice Cores, Pollen Records.

Why do scientists study ancient climates?

They can persist in rocks and ice for thousands to millions of years, so they are useful if we want to know about past conditions at Earth’s surface. For example, some water molecules are “heavier”, containing isotopes of hydrogen and oxygen with more neutrons.

Which describes one characteristic of both El Niño and La Niña quizlet?

Which describes one characteristic of both El Niño and La Niña? Both are causes of long-term climate change.

Why are pollen grains useful when studying the climate history of a region?

Why are pollen grains useful when studying the climate history of a region? … They may have rings inside them that reflect variations in the local climate. They can be preserved within the fossils of organisms that carry them. They provide clues about the types of plants that grew in a region at a particular time.

How can scientists learn about the Earth’s climate history quizlet?

What are two ways that scientists can study how earth’s climate has changed over time? They can look at tree rings, they can study long cylinders of sea-floor sediment taken from the ocean floor, and they can study sample cylinders of ice taken from the ice caps called ice cores.

How do scientist use ice to study ancient climates quizlet?

Scientists can study tree rings in ice to learn more about past climates. Scientists can drill deep into the ice to collect ice cores.

What do glaciers deposit that helps scientists study ancient climates quizlet?

Ice cores are cylinders of ice drilled from ice sheets and glaciers. They are essentially frozen time capsules that allow scientists to reconstruct climate far into the past.

How do scientists use Varves to study past climate?

Varves can be counted to determine the age of the sediment, and the pollen and spores within the sediment can be extracted to see what types of vegetation were present at different times.

What techniques are used to learn about past climates and environments?

Paleoclimatology is the study of past climates. Since it is not possible to go back in time to see what climates were like, scientists use imprints created during past climate, known as proxies, to interpret paleoclimate. Organisms, such as diatoms, forams, and coral serve as useful climate proxies.
