Precambrian era. It encompasses the vast stretch of time from the formation of Earth around 4.6 billion years ago up until the beginning of the Phanerozoic eon around 541 million years ago. This era is divided into the Hadean, Archean, and Proterozoic eons, and marked by the development of Earth's atmosphere, oceans, and early life forms.

Major divisions of earths history are?
The major divisions of Earth's history are typically divided into eons, eras, periods, and epochs. The current eon is the Phanerozoic, which is divided into eras such as Paleozoic, Mesozoic, and Cenozoic. Each era is further divided into periods, like the Jurassic period within the Mesozoic era. Periods can be subdivided into epochs, such as the Pleistocene epoch within the Quaternary period.

25% is absorbed by clouds.25% is reflected by clouds.So 50% of the sun's radiation is lost before it reaches earth's surface.See the diagram link below.
What type of eruption produces a viscous magma containing 53 percent silica and a gas content of 2 percent?
A type of eruption that produces a viscous magma with 53 percent silica and a gas content of 2 percent is typically associated with a stratovolcano or a composite volcano. These eruptions are explosive due to the high viscosity of the magma, leading to the buildup of gas pressure before an explosive release. Example volcanoes with this type of eruption style include Mount St. Helens in the United States and Mount Pinatubo in the Philippines.
