What fraction or percent of geologic time have land plants been on earth Show your work?
Land plants have been on Earth for about 450 million years out of the total 4.6 billion years of geologic time, which is about 9.8% of Earth's history. This calculation is based on the estimated timeline of the first appearance of land plants in the Ordovician period around 450 million years ago.
What else can I help you with?
About 88 percent of geologic time is represented by the time span called what?
The Precambrian Eon represents about 88 percent of geologic time on Earth. This eon includes all time prior to the Paleozoic Era and spans from the formation of the Earth about 4.6 billion years ago to the beginning of the Paleozoic Era around 541 million years ago.
The division of geologic time that makes up about 88 percent of Earth's history is called?
The division of geologic time that makes up about 88 percent of Earth's history is known as the Precambrian Eon. It is the longest eon and encompasses the time from the formation of Earth around 4.6 billion years ago to the beginning of the Paleozoic Era around 541 million years ago.
Seventy-five percent of the Earth and acirc and 128 and 153s biomass is contained in?
Seventy-five percent of Earth's biomass is contained in plants.
Which era of geologic time spans about 87 percent of Earth's history?
The Precambrian era spans about 87 percent of Earth's history. It includes the Hadean, Archean, and Proterozoic eons and is characterized by the formation of Earth, the development of early life forms, and significant geological events.
Which of the following is not a geologic period of the Earth Jurassic Cretaceous Triassic Neoprene?
Neoprene is not a geologic period of the Earth. The Jurassic, Cretaceous, and Triassic are all recognized geologic periods that represent different intervals of time in the Earth's history.
For what fraction of geologic time life has existed on earth for what fraction of geologic time have human existed on the earth?
Approx 1/22500 of it.
What fraction of geological time have land plants been present on earth?
Approximately : land plants have been around for a half a billion years. The Earth for 4.5 billion years. So your answer is one ninth.
About 88 percent of geologic time is represented by the time span called what?
The Precambrian Eon represents about 88 percent of geologic time on Earth. This eon includes all time prior to the Paleozoic Era and spans from the formation of the Earth about 4.6 billion years ago to the beginning of the Paleozoic Era around 541 million years ago.
How does the existence of people on Earth compare with the length of geologic time on Earth?
The existence of people on Earth is relatively short compared to the length of geologic time on Earth. Humans have been around for only a tiny fraction of Earth's history, which spans billions of years. Geologic time encompasses vast scales of time, with the history of humanity representing just a minuscule portion of it.
