The Geologic History Of Earth Note The Timescales We Are Currently In Which era of geologic time spans about 88% of earth's history? a. precambrian b. paleozoic c. mesozoic d. cenozoic e. none of the above 10. the means "the sun in the making." a. solar disk b. presun c. nebular sun d. sol e. protosun 11. mammals became the dominant land animals during the era. a. pleistocene b. cenozoic c. cretaceous. 4,500,000,000 43,200 = 104,167. 0.5 second = 52,083 years. 1 second = 104,167 years. 1 minute = 6,250,020 6.25 ma years. 1 hour = 375,001,200 375 ma years. humans > 2 ma years = 19 seconds. this infographic offers a visual way to explore the various stages of the earth's history using a 12 hour clock analogy.
Investigate юааearthюабтащюааsюаб Geologic юааhistoryюаб Students Will Understand How Description. this interactive module allows students to explore the science of earth's deep history, from its formation 4.5 billion years ago to modern times. earthviewer dynamically shows how continents grow and shift as students scroll through billions of years. additional layers let students explore changes in atmospheric composition. September 30, 2014. 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. Earth’s timeline and history. 4,567,000,000 years ago, earth was covered in molten lava. earth was completely unrecognizable. in its earliest stage of formation, it was uninhabitable as it clumped from a cloud of dust. about 1,000,000,000 years ago, earth had its first signs of life. single celled organisms consumed the sun’s energy. The geological history of the earth follows the major geological events in earth's past based on the geological time scale, a system of chronological measurement based on the study of the planet's rock layers ( stratigraphy ). earth formed about 4.54 billion years ago by accretion from the solar nebula, a disk shaped mass of dust and gas left.

The geologic time scale is the “calendar” for events in earth history. it subdivides all time into named units of abstract time called—in descending order of duration— eons, eras, periods, epochs, and ages. the enumeration of those geologic time units is based on stratigraphy, which is the correlation and classification of rock strata. By. alex bolano. over 4.5 billion years ago, our solar system formed from a giant molecular cloud that collapsed under its own tremendous gravity. the hot stew of hydrogen and helium gave birth to our sun and flung out a wide disc of gas and particles in the surrounding space. over millions of years, this disc of gas coalesced into the planets.
