Answer

A, B, C, D Explanation 1. Identify key early Earth features Early Earth was extremely hot due to formation heat and frequent asteroid impacts. 2. Identify water coverage Volcanic activity and condensation eventually created vast oceans covering most of the surface. 3. Identify atmospheric composition Atmosphere lacked free oxygen; composed mainly of CO₂, N₂, water vapor, and other gases. 4. Identify protective layers No ozone layer existed without oxygen, so harmful UV radiation reached the surface.
