A student visits the beach during a very hot day. She steps on the sand and jumps because it is so hot
Mama L [17]

Answer:

A student visits the beach during a very hot day. She steps on the sand and jumps because it is so hot as a result of "conduction."

Explanation:

The process of the conduction happens because of the flow of kinetic energy from one molecule to the other by direct contact.  When she first steps the beach on the hot sand, after that the energy moves from the hot sand to the cooler body by conduction. While walking on the sand for few time, the feet will feel hot. The movement of the heat takes place from the hot sand to the bottom of the feet by conduction. When the objects come in contact with each other the heat transfers as a result of conduction.

When you open the door to your house on a cold day, you feel a cold draft. What causes
wariber [46]

Answer:

4. Warm air from the inside moving toward the cold air outside.

Explanation:

A cold draft can be defined as the process in which a current of cold air is being drawn in from the outside. Also, it involves the process in which a current of warm inside air exits or leaves a building through an opening.

This ultimately implies that, when you open the door to your house on a cold day, you would feel a cold draft as a result of the movement between the warm air from the inside moving toward the cold air outside. The warm air that were trapped inside your house would escape through the door due to a difference between the outside (cold) and inside (warm) atmospheric pressure.

Hence, a difference in temperature and atmospheric pressure between the outside and inside air usually causes a cold draft.

<em>Additionally, air typically moves or travels from a region of high pressure to a region of lower pressure. </em>

harkovskaia [24]

Answer:

Pauline and David are talking about the use of resources in a sustainable manner so that both humans and living organisms can co-exist and enjoy the benefits of nature. Pauline is a conservationist whereas David lives in a biodiversity hot spot. The conversation starts when David and Pauline meet in an ecology conference. Pauline is standing in front of poster talking about conservation of environment and wildlife. David pass by and see that the topic is quite interesting.

David: Hey, I like your topic of presentation.

Pauline: Thank you! are you also a conservationist?

David: I wish I could be but my job nature doesn't allow me to work in this area. However, I truely care about the wildlife which are being threatened in my neighbourhood...

Pauline: Oh, I am sorry to hear that... Where do you live?

David: I live between the city and forest, which is being affected by humans interventions. I see everyday a lot of animals dying on roads because they are forced to migrate because of forest cutting, however, while doing so, they are killed by human's actions.

Pauline: I absoultely hate this behavior of humans. I think human's should understand the importance of other organisms in biogeochemical cycles otherwise our generations are going to pay a lot for this.

David: Definitely, I wish we could reverse such decisions but again, they are not easy. With growing human's populations, we need to adjust everything accordingly.

Pauline: You are right. But we can develop strategies where both humans and animals can live in hormony, such as development of ecological corridors in a forest if we want to make a road, could help these creatures to survive well.

David: I cannot agree more. I hope such things are encouraged in near future. But I really liked your idea and would like to discusss sometime later.

Pauline: Sure, you can visit me anytime in my office at XYZ location.

David: Thank you, see you than!

Pauline: See you!
