how does the high heat capacity of water affect how water shapes the earth?
the high heat capacity of water means that most of the water on earth will be in the form of water vapor.
the high heat capacity means a lot of the water on earth will exist in liquid form.
the high heat capacity of water means that water will not move very much through the hydrologic cycle, it will stay in one place.
the high heat capacity of water means that water can move faster on earth than other liquids.

Explanation:

First Question (Specific Heat Capacity Definition)

The definition of specific heat capacity is the amount of heat energy required to raise the temperature of 1 unit mass (usually 1 gram or 1 kilogram) of a substance by 1 degree Celsius (or 1 Kelvin). The question's statement matches this definition (note: sometimes it's per unit mass, but the core idea of heat for 1 degree temp rise of the substance is correct here).

• Option 1: High heat capacity doesn't mean most water is vapor (vaporization needs heat, and high heat capacity means water resists temp change, not that it's vapor). Eliminate.
• Option 2: High heat capacity means water requires a lot of heat to change temperature/state, so it stays liquid over a wide temp range on Earth. This allows liquid water to exist, which is key for erosion, weathering, and the hydrologic cycle that shapes Earth. Correct.
• Option 3: High heat capacity doesn't restrict water movement in the hydrologic cycle (water moves via evaporation, precipitation, etc., regardless; heat capacity relates to temp change, not movement restriction). Eliminate.
• Option 4: Heat capacity doesn't relate to water's speed of movement (movement is due to gravity, pressure, etc., not heat capacity). Eliminate.

Answer:

True
