1. Suppose you go to the beach in the morning on a sunny summer day. Explain the rate at which thermal energy is absorbed by the water, sand, and air during the day.

2. Explain why the flow of energy between air and sand is different than that between air and water as thermal energy is absorbed from day to night.

3. As the Sun begins to set, predict the effect on the rate at which the air, water, and sand cool

4. Explain why the flow of energy between air and sand is different than that between air and water as thermal energy is RELEASED.

Answers

Answer:

1. During the day, the sun heats up both the ocean surface and the land. Water is a good absorber of the energy from the sun. The land absorbs much of the sun’s energy as well. However, water heats up much more slowly than land and so the air above the land will be warmer compared to the air over the ocean.

2.The air over the ocean is now warmer than the air over the land. The land loses heat quickly after the sun goes down and the air above it cools too. This can be compared to a blacktop road. During the day, the blacktop road heats up and becomes very hot to walk on. At night, however, the blacktop has given up the added heat and is cool to the touch. The ocean, however, is able to hold onto this heat after the sun sets and not lose it as easily. This causes the low surface pressure to shift to over the ocean during the night and the high surface pressure to move over the land. This causes a small temperature gradient between the ocean surface and the nearby land at night and the wind will blow from the land to the ocean creating the land breeze.

3. The sand should both heat and cool faster than the water. This is because water has a higher specific heat ca- pacity than sand – meaning that it takes a lot of heat, or energy, to raise the temperature of water one degree, whereas it takes comparatively little energy to change the temperature of sand by one degree.

4.

Based on heat flow, land and sea breezes occur due to differences in the heat capacities of air, land and sea

What is thermal energy?

Thermal energy is the energy due to temperature difference between two bodies.

Thermal energy or heat flows from hotter to colder bodies.

The flow of thermal energy between air, land and sea results in land and sea breezes.

On a sunny beach, the thermal energy absorbed by the water sand and air.

Water absorbs the most heat due its high heat capacity, while the air gets heated up easiest due to its low heat capacity.

The sand absorbs heat faster than the water and feels hot when stepped on.

As the land is heated faster than oceans, air over land is warmer than air over the water, thus, warm from land rises and is replaced by cold air from the ocean.

As the sun sets, due to the differences in their heat capacities, the air loses heat fastest, then followed by land while the ocean loses the least heat.

As the land loses heat faster than oceans, air over land is colder than air over the water, thus, cold from land replaces warm air from the ocean as it rises.

The levels of chlorine used for disinfection of drinking water causes long-term health effects because chlorine is toxic substance that greatly damaged cells and tissues of our body. Chlorine has low protection against protozoa due to its ineffectiveness on the protozoans organisms. These protozoa also adversely affected our health so we can say that chlorine has to be used in a limit which does not harm our body.

Please help Why must animals eat food but plants do not eat food?(1 point) Plants do not appear to eat, but they do actually eat nutrients in the soil. Animals must eat to obtain food that they can't get from the soil. Plants make their own food through photosynthesis, so they do not eat. Animals eat because the energy they make themselves is enough to live but not grow. By eating, they can grow big and strong. Plants use photosynthesis to make their own food instead of eating. Animals eat plants because they like the taste of certain fruits. Plants make their own food through photosynthesis. Animals must eat because they cannot make their own food.

Select all the correct answers. Kangaroo rats are organisms found in the desert. Deserts have a hot, dry climate. Which three adaptations must kangaroo rats possess to survive in these conditions? fewer sweat glands nocturnal behavior presence of thin coats increased water retention ability bright-colored skin
fewer sweat glands
nocturnal behavior
presence of thin coats
increased water retention ability
bright-colored skin

Answers

The three adaptations that kangaroo rats must possess to survive in a hot, dry climate are fewer sweat glands, the presence of thin coats, and increased water retention ability.

What do you mean by Adaptation?

Adaptation may be defined as the accommodation of organisms to their environment in order to enhance their possibilities of survival in that environment.

Kangaroo rats must live in a hot, dry climate. They have fewer sweat glands because this prevents the loss of excessive fluids outside the body of the kangaroo.

Due to the warm and humid climate of the desert, they have better water retention capability to prevent the condition of excessive thirst.

The presence of a thin coat that is oily. They maintain this coat with hygienic dust or sand which helps them to keep the proper level of oil in the fur and prevents water loss.

Therefore, the three adaptations that kangaroo rats must possess to survive in a hot, dry climate are fewer sweat glands, the presence of thin coats, and increased water retention ability.
