The ancestors of invertebrates produced enough oxygen to oxidize minerals dissolved in the ocean and surface sediments through a process called respiration.

Answer to Question 1

False

Answer to Question 2

 Heat capacity is the amount of energy required to raise one gram of a substance by 1 Celsius. Water has one of the highest heat capacities, seconds only to ammonia.
 Latent heat is the pause in temperature fluctuations when water is changing states. Latent heat of fusion occurs when liquid water becomes ice. The addition of 80 calories per gram is needed for water to become a solid. Latent heat of vaporization happens when water is transitioning to a gas. This state change requires 540 calories per gram. These properties make it easier for water to remain in a liquid state.
 Water's high heat capacity allows it to absorb large amounts of heat from the sun, but only raise a few degrees in temperature. The tendency to resist temperature changes when heat is gained or lost is called thermal inertia.
 These properties of water keep the ocean at a relatively consistent temperature and in a liquid state. This is a big factor in keeping the Earth cool.
