How do we know what ancient climate was like?
Clues about the past climate are buried in sediments at the bottom of the oceans and lakes, locked away in coral reefs, frozen in glaciers and ice caps, and preserved in the rings of treesTo extend those records, paleoclimatologists look for clues in Earth's natural environmental records.
What evidence provides evidence of past climates?
Tree rings, ice cores from Greenland and Antarctica, sediments from the bottoms of lakes and seas, and many other natural proxy records of climatic conditions help us piece together the story of Earth's climates from the ancient past.
What is ancient climate?
The climate of ancient Earth is called its paleoclimate, and scientists study it to understand how Earth's climate might change in the future.
Which of the following is the study of ancient climates?
Paleoclimatology is the study of ancient climates. The origin of the word is from the Greek word "paleo," which means ancient. Paleoclimatologists are scientists who study the ancient climate. Paleoclimate occurred before our modern weather instruments, such as thermometers, rain gauges, or barometers existed.

How can we determine the past climate behaviors?
How do we determine past climate?
- Ice cores: The ratio of oxygen isotopes in ice indicates the temperature at the time ice was deposited as snow. …
- Fossil pollen: Different classes of plants produce pollen grains with different distinctive shapes.
What was the climate like in the past?
The Earth's first billion years were very different from the conditions today. The sun was cooler then, but the planet was generally warmer. That's because there were a lot of greenhouse gases, like carbon dioxide and methane, in the atmosphere. Also, the atmosphere back then contained very little oxygen.
How does evidence of ancient climates support continental drift?
Wegener used fossil evidence to support his continental drift hypothesis. The fossils of these organisms are found on lands that are now far apart. Grooves and rock deposits left by ancient glaciers are found today on different continents very close to the equator.
What are the 4 cause of climate change?
Burning fossil fuels, cutting down forests and farming livestock are increasingly influencing the climate and the earth's temperature. This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming.

What caused climate change in the past?
Earth's climate has changed dramatically many times since the planet was formed 4.5 billion years ago. These changes have been triggered by the changing configuration of continents and oceans, changes in the Sun's intensity, variations in the orbit of Earth, and volcanic eruptions.
What were the 4 main evidence of continental drift?
The four pieces of evidence for the continental drift include continents fitting together like a puzzle, scattering ancient fossils, rocks, mountain ranges, and the old climatic zones' locations.
What are the 5 evidences of continental drift theory?
They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils.
What are the 3 main natural causes of climate change?
These have been caused by many natural factors, including changes in the sun, emissions from volcanoes, variations in Earth's orbit and levels of carbon dioxide (CO2). Global climate change has typically occurred very slowly, over thousands or millions of years.

What are the 4 natural causes of climate change?
The earth's climate is influenced and changed through natural causes like volcanic eruptions, ocean currents, the Earth's orbital changes, solar variations and internal variability.

How did Wegener explain why fossils of land animals were found on continents that are across oceans from one another?
How did Wegener explain why fossils of land animals were found on continents that are across oceans from one another? – Animals evolved separately on each continent.
How rocks fossils and climate provided evidence of continental drift?
How did fossils provide evidence for continental drift? Similar fossils occur on different continents. Because many of these organisms could not have crossed an ocean, this provides evidence that the continents were once connected.
