1. Early earth had no ozone layer, which means it was most likely extremely hot.
2. Young earth had no oxygen and life needs oxygen in order to survive.
3. There where so many natural disasters happening all the time, like volcanic eruptions and constant impact with meteorites and asteroids.
-Extra one (4. Earth originally had no ocean and water. Oceans eventually formed from the water vapor released from the volcanic eruptions, but before that there was nothing.)
Answer:
Australia has so many genetically distinct organisms because it has been separated from other bodies of land for a very long time. This has given species in Australia a long time to evolve independently from species in other areas of the world.
Answer:
In the process of photosynthesis, trees tend to take up carbon dioxide and water and convert it into oxygen and glucose. In this way, trees help in reducing the amount of carbon dioxide from the air which is otherwise a source of global warming. The process of photosynthesis also yields oxygen which is beneficial for life on earth.
The trees also store carbon inside them hence, reducing global warming. The more the trees, the more will be the chances of carbon being reduced from the atmosphere and being stored in the trees.
Plant processes like transpiration help to lower the temperature around them. Hence, more the trees, lesser will be the rise in temperature.
Answer: Condensation
Water vapor is water in a gaseous state. Transformation of water into gaseous state
(water vapor) is called evaporation. Transformation of the water vapor into dew
which Michael observed in the early morning is called condensation.
Dew<span> is water droplets
that appears on exposed objects like
leaves in the morning or evening due to condensation</span>
