Why is urbanization contributing to pollution? people in urban areas strip the soil of nutrients and make it difficult to grow crops. people in urban areas consume more energy, food, and water. people in urban areas remove minerals and metals from the ground, which increases erosion. people in urban areas log forests and mine, which causes climate change.

People in urban areas consume more energy, food, and water. That is the main reason of pollution in urban areas. The more use of energy leads to shortcoming of resources. Thus lesser or unsustainable environment conditions.

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
