earths atmosphere, and the gases in it, has evolved over time. cyanobacteria (microscopic organisms) developed in earths oceans as earths first photosynthetic organisms - releasing oxygen into the atmosphere. as they evolved, enough oxygen was released that many new life forms (like us) could evolve on land utilizing the atmospheric oxygen!

Explanation:

Question 3

Volcanic ash comes from volcanoes (part of the lithosphere, which includes the Earth's crust and upper mantle). The ash enters the atmosphere and affects solar radiation and weather (atmospheric processes). So the interaction is between the lithosphere (source of volcanic ash) and the atmosphere (where the ash acts to block radiation and influence weather).

Cyanobacteria are photosynthetic organisms that first appeared in Earth's oceans. Photosynthesis by cyanobacteria releases oxygen. Over time, this oxygen accumulation in the atmosphere allowed aerobic life forms (including those on land) to evolve. This is a well - known part of Earth's atmospheric and biological evolution.

The biosphere consists of all living organisms and the areas they inhabit. Trees are plants (living organisms), and bacteria are microorganisms (also living). Volcanoes are part of the lithosphere (geological features, non - living), and gases are part of the atmosphere (non - living in terms of the biosphere's definition of living organisms and their habitats).

Answer:

Atmosphere, Lithosphere
