The Precambrian time refers to the time 4.5 billion to 542 millions year ago. This period is characterized by having reduced atmosphere and included reduced compounds. Scientists believed that atmosphere at that time was devoid of free oxygen and CO2 was present in excess. Before the complex life evolved on the Earth, the Precambrian Earth's ocean contained dissolved carbon dioxide.
The answer is 100%. Three are observable, but the fourth is just a carrier.
Evaporation
Explanation:
Evaporation is one change that would cause more water to evaporate from a stream.
Evaporation is a phase change in which liquid is changed into its gaseous form.
- When a substance is heated from solid to liquid, it melts.
- After melting, additional heat causes a phase change that allows for the liquid to change to gases.
- In the water cycle, the sun provides heat energy that causes surface water in streams to be heated.
- This leads to evaporation of the surface water into the atmosphere where they can be condensed to form precipitation.
