The fossil record provides a glimpse into the evolution of life on Earth. It shows that there have been remarkable changes in th
e kinds of organisms that have been abundant at different times during the past 3.5 billion years. The history of life according to the fossil record.Classify each event in the history of life into the appropriate eon or era.Drag each phrase to the appropriate bin.
The Proterozoic Eon continued for about 2,500 to 541 mn years ago and it preceded the Archean. Consisting of the deepwater deposits and the strata, and showed a rapid continental acceleration and the occurrence of the first known glaciations also to place.
The paleozoic eon was for about 542 to 251mn years ago and it was divided into the six geological period ad they started after the breakup of the supercontinent as Pangea.
The archean eon is an eon that was for about4,000 to 2,500 mn years ago with a tectonic layer of rocks and rocks were more active than they are now. Formation of the mudstone and the volcanic sediments.
The Mesozoic era was about 252 to 66 mn years ago and it was the age of reptiles and the coniferous, as Mesozoic is the middle life and is one of the three eras of the Phanerozoic eon.
Cenozoic is a new life and is the most recent phase of the geologic eras. ad extends from about 66 mn yer ago. Known as the extinction event of the earth.
Hadean eon stared with the formation of the earth 4.6 billion years ago.
Explanation:Media commentators prefer to report economic data that have not been adjusted for changes in the price level because of the fact that without making any adjustments for changes in price level leads to a number that is much higher.
<span>Mercury's distance at inferior conjunction is 0.61 AU
Looking at a table of orbits, Mercury has an orbital distance of 0.39 AU. So the inferior conjunction will be:
1 AU - 0.39 AU = 0.61 AU</span>
March equinox is day during the year when all the daylight of the sun is asme at sunrise and sunset.
Explanation:
Equinox is the time when the plane of the earth passes through the centre of the sun. Occurring around 23 March and 23 Sept. The vernal equinox is also called as the spring equinox.
The azimuth of the sun is the angle of the sun's position defined by the relative direction along the horizon. However the most commonly followed convection for analyzing the sun radiation is 90 degrees east, south 180 degrees and west is 270 degrees.
As sunrise and sunset are defined by the upper limb of the solar disk. These conditions produce patterns of night and day as the sun appears to move just above the horizon at an angle of 0.39 degrees per day as the equinox passes.
