Explanation:
The Northern lights are located at the Thermosphere of the atmosphere. The Thermosphere is lies beyond 80 km above the mesopause. The properties of gases are not constant in this layer. temperature increase rapidly with the increase of height. There are number of ionic layers in this sphere. The layer called D disappears with the sunset as it associated with solar radiation.
Answer:
1)diaphragm vibrations- sound waves
2) Changing magnetic fields- Electrical energy
3)sound waves- Mechanical energy
Explanation:
A changing magnetic field induces an electromotive force and then an electric field which contains electrical energy
Sound energy is a form of energy that can be heard by humans. Sound is an example of a mechanical wave because it consists of physically oscillatory elastic compression.
A diaphragm is a thin surfaced cone used to produce sound. It is caused to vibrate using electromagnetic energy.
Correct answer: B). Shelter wood cutting takes place over several years
Shelterwood cutting is the progressively cutting of the forest, in order to establish the growth of the new generation of the seedlings of a particular species without planting.
It is a method of natural tree reproduction under the shelter of old trees, which are removed successively by cutting the tree in order to provide the increased amount of light to the new seedlings. It is a slow process and takes lot of time.
