Over the last 540 million years, icecaps covered at least one of the Earths poles during three intervals. Ron Blakey is professor emeritus of geology at Northern Arizona University and founder of Colorado Plateau Geosystems Inc. Exploring Earths Climate with EarthViewer.

Slide through the timeline above to explore how the globe has changed over seven major “snapshots” in our climate history, and to see how it might look in the far future.Īlex Tait is Vice President of International Mapping in Ellicott City, Maryland. Tips for using the App: Spin the Earth with your finger to get a 360-degree view of the world Zoom in or out by pinching or spreading your fingers on the screen Use the silver slider to view the changing Earth through geologic time To switch between the three timelines, use the pinch or spread gesture Select CHARTS to explore data on. Use the EarthViewer features to fill in the following chart. Exploring Science Earth Science Weather and Climate. Students read a passage about the interaction of geology and the carbon cycle. Use the CHART button to find an approximate temperature range for the three intervals. Learn science exploring earth's weather with free interactive flashcards. 67 Users Share This Description This activity guides students through building a conceptual model of how carbon dioxide affects Earth’s climate. When were those intervals Paleogene period Neogene period Quaternary period b. Understanding how humans are affecting Earth’s system requires a better grasp on the natural cycles and events that have shaped our planet through deep time. Over the last 540 million years, icecaps covere d at least one of the Earth’s poles during three intervals. But scientists agree that human activity has now begun to influence the planet, changing the climate and drastically altering surface conditions. This constant reconfiguration has been a huge driver in the development of life on Earth. 10042 Hhmi Deep History Of Life On Earth Answer Key NEW 289 kb/s 9862 Deep History Of Life On Earth - HHMI BioInteractive Description This interactive module explores key events in the record of life on Earth, which stretches over three billion years. What did Earth look like 4.5 billion years ago, and what was the climate. This beam then enters a magnetic field $B$ at right angles to the field and is bent into a quarter circle.Earth is a planet defined by change, swinging through periods of intense heat and deep freeze even as oceans and continents are reshaped by the actions of plate tectonics. This EarthViewer Climate Guide Activity Activity is suitable for 9th - 12th Grade. In one method for separating these isotopes, a sample containing both of them is first singly ionized (one electron is removed) and then accelerated from rest through a potential difference $V$. Climatologists can determine the past temperature of the earth by comparing the ratio of the isotope oxygen-18 to the isotope oxygen- 16 in air trapped in ancient ice sheets, such as those in Greenland.
