Question

sunlight carries energy. this energy is absorbed by the oceans in the form of heat. the heat spreads through the ocean and warms the ocean. this heat keeps warm water fish at just the right temperature, which is very important for their survival. which method transfers heat from the sun to the ocean? dropdown which method spreads heat in the ocean? dropdown which method transfers heat from the ocean to the fish? dropdown

Explanation:

To solve these questions, we analyze the heat transfer methods (radiation, convection, conduction) for each scenario:

1. Heat transfer from Sun to Ocean

The Sun transfers heat to the ocean through radiation (heat transfer via electromagnetic waves, which can travel through empty space).

2. Heat spread within the Ocean

In fluids (like ocean water), heat spreads mainly through convection (heat transfer by the movement of fluid currents, as warmer water rises and cooler water sinks).

3. Heat transfer from Ocean to Fish

Heat transfers from the ocean (warmer water) to the fish (cooler body) through conduction (direct heat transfer between objects in contact, as the fish is in contact with the ocean water).

Answer:

s:

• Which method transfers heat from the Sun to the ocean? $\boldsymbol{\text{Radiation}}$
• Which method spreads heat in the ocean? $\boldsymbol{\text{Convection}}$
• Which method transfers heat from the ocean to the fish? $\boldsymbol{\text{Conduction}}$
