There was lava everywhere, and there were a lot of rain. It was very hot, with an extremely high amount of carbon dioxide in the air. In a way, it looked like the sun, but much smaller. The lava gradually started to cool down and turned into solid land as time ticked down toward the Cambrian period. At the beginning, there were near-boiling point hot spring that housed our ancestors, the archeobacteria (i think), which could survive the heat.
It was almost an entire world of nothing but ocean. there were many strange organisms that lived in the water.
During the Precambrian period, plants had not yet evolved. The Precambrian period is characterized by simple life forms like bacteria and algae. Land plants did not appear until the Ordovician period, which followed the Precambrian.
During the Precambrian time period, Earth was dominated by oceans and did not have many of the familiar features we see today, such as abundant plant and animal life or complex land formations. The atmosphere had high levels of gases such as methane and carbon dioxide, and the surface was mostly barren with simple life forms like bacteria and algae.
During the Precambrian period, there were no plants as we know them today. The Precambrian period mainly featured simpler life forms like algae and cyanobacteria. It was not until the Paleozoic era that plant life diversified and evolved into more complex forms.
During the Precambrian time period, the Earth's surface was dominated by rugged terrains and volcanic activity. There were no complex life forms, and the atmosphere did not contain much oxygen. Land masses were forming and breaking apart, leading to the creation of early continents.
The Precambrian time is the longest part of Earth's history, spanning from the formation of Earth around 4.6 billion years ago to about 541 million years ago. It makes up about 88% of Earth's history.
During the Tertiary Period, the surface of the earth looked much like it does today. It was quite warm with periods of cold much like today.
Over most of Precambrian time 80 percent of earths history-the only life forms are bacteria ,which appear about 3,500 million years ago. multiple-cells marine animals like spriggina appear at the end of the era
it was alphabet soup
There were no trees in the Precambrian Super-Eon (4576.2 - 542Ma). There were plants in the Precambrian. Simple green algae associated with aquatic environments were thought to evolved around 2.5 billion years ago during the Proterozoic Era. It was not until the Cambrian Period 510 million years ago, the 1st complex land plants evolved. The first trees do not appear in the fossil record until the Late Devonian Period about 385 million years ago.
During the Precambrian period, significant changes occurred in the atmosphere. Early in the period, the atmosphere was primarily composed of gases like methane, ammonia, and carbon dioxide with little to no oxygen. But over time, due to the emergence of photosynthetic bacteria, oxygen levels began to rise, leading to the development of an oxygen-rich atmosphere by the end of the Precambrian. This rise in oxygen was a major milestone in Earth's history, paving the way for the evolution of complex multicellular life forms.
Some processes that help shape the Earth's surface in Precambrian shields include tectonic activity, such as mountain building and plate movements, erosion from wind and water, and volcanic activity. These shields have experienced billions of years of geologic processes, leading to the formation of various landforms like mountains, valleys, and plains.
