How does afforestation help to control flood and landslide.​

Afforestation. Trees are planted near to the river. This means greater interception of rainwater and lower river discharge . This is a relatively low cost option, which enhances the environmental quality of the drainage basin .

Trees prevent floods, landslides

They help the groundwater supply recharge, prevent the transport of chemicals into streams and prevent flooding. ... The trees' roots suck water deep from under the ground to as low as 200 feet. They hold the soil together so that erosion is prevented.

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.

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.
