Answer:
Explanation:
Ice cores can tell scientists about temperature, precipitation, atmospheric composition, volcanic activity, and even wind patterns. The thickness of each layer allows scientists to determine how much snow fell in the area during a particular year.
The vast majority of energy in food webs originates from the sun. Energy is not recycled in ecosystems and each ecosystem requires a continuous input of energy to sustain it. There is some energy transformed at each level of the food chain or food web in an ecosystem.
Explanation:
they are likely to be lost.
Chain reaction
Nuclear energy
Explanation:
Question 1:
Chain reaction:
A reaction in which when one occurs, it starts a series of other fission reaction is called a chain reaction.
Most nuclear reactions are chain reactions in which does not come to rest in one step like chemical reaction.
In nuclear reactions like which fusion and fission, one step leads to another until an atom attains stability or a stable product is formed.
The energy needed to sustain the chain process is produced in the previous reaction.
Nuclear energy:
The type of energy used in a nuclear power plant is called a nuclear energy. Nuclear energy is used to generate power in nuclear plant.
During a nuclear decay process, a huge amount of energy is released. This energy is channeled into electricity production and to do other useful works.
Nuclear energy is classified as a non-renewable source of energy.
