Which of the following is an example of a proxy indicator?

There are four main types of proxy climate indicator, for example, which are historical (oral or written records), biological (records of faunal and floral growth and distribution), geological (terrestrial deposits and features, and marine ocean sediment cores), and glaciological (ice cores).

What can ice cores tell us about Earth’s history quizlet?

Looking at snowfall in ice cores over such a long period of time can provide clues to climate change by providing evidence of temperature, precipitation, and atmospheric conditions.

Which of the following best describes how ice cores are used as proxy indicators of past climates quizlet?

Which of the following best describes how ice cores are used as proxy indicators of past climate? The ice traps air bubbles of the past climate in annual layers of ice.

What kind of information do ice cores contain?

Ice cores can tell scientists about temperature, precipitation, atmospheric composition, volcanic activity, and even wind patterns. The thickness of each layer allows scientists to determine how much snow fell in the area during a particular year.

Which of the following is an example of proxy indicator of climate change?

Examples of proxies include stable isotope measurements from ice cores, growth rates in tree rings, species composition of sub-fossil pollen in lake sediment or foraminifera in ocean sediments, temperature profiles of boreholes, and stable isotopes and mineralogy of corals and carbonate speleothems.

Which of the following is an example of proxy data indirect evidence of past climate conditions?

– Proxy indicators are types of indirect evidence that serve as substituted for direct measurement & that shed light on past climate. Examples of proxy indicators are ice cores, tree rings, sediment beds, and coral reef.

How do greenhouse gases warm the lower atmosphere quizlet?

How do greenhouse gases warm the lower atmosphere? as Earth’s surface absorbs solar radiation, the surface increases in temperature and emits infrared radiation. After absorbing radiation emitted from the surface, greenhouse gases re-emit infrared radiation.
