which events contributed to life evolving on earth? check all that apply. organisms began to photosynthesize. the surface cooled, and water condensed. volcanoes added carbon dioxide to the atmosphere. ozone formed and blocked ultraviolet rays from the sun. comets crashed into earth, releasing water.

Answer

Brief Explanations:

  • Organisms photosynthesizing produced oxygen, crucial for life evolution.
  • Surface - cooling and water condensation provided habitats for early life.
  • Volcanoes adding carbon - dioxide contributed to the atmosphere composition for life.
  • Ozone formation protected organisms from harmful UV rays.
  • Comets crashing and releasing water added to the water supply for life.

Answer:

All of the above (Organisms began to photosynthesize; The surface cooled, and water condensed; Volcanoes added carbon dioxide to the atmosphere; Ozone formed and blocked ultraviolet rays from the Sun; Comets crashed into Earth, releasing water)
