Vhich event in Earth's history was dependent on the development of a certain type of life-form? 1) addition of free oxygen to Earth's atmosphere 3) movement of tectonic plates B) formation of clastic sedimentary rocks D) filling of the oceans by precipitation

Answer 1

A) addition of free oxygen to Earth's atmosphere

Answer 2

The event in Earth's history that was directly dependent on the development of a certain type of life-form is the addition of free oxygen to Earth's atmosphere. This significant rise in atmospheric oxygen, known as the Great Oxidation Event, was facilitated by the photosynthetic activity of cyanobacteria. These microorganisms produced oxygen as a byproduct of photosynthesis, which eventually accumulated in the Earth's atmosphere.
