Fission and fusion are nuclear reactions that produce energy, though they are not the same. Fission is the splitting of a heavy and unstable nucleus into two lighter nuclei. Fusion is the process where two light nuclei combine together releasing vast amounts of energy.
Answer: By either emigration or natural increase.
Explanation: Natural increase is where in a population, the birth rate, or number of live births per year, is greater than the death rate, or deaths per year. Emigration is when individuals leave their region to move to another, often due to economic or political reasons. Eventually, a population will reach its carrying capacity, where the land the population occupies is only just able to support the population. Once the carrying capacity is breached, the population will start to collapse.
Answer:Four spheres of earth are:1)Lithosphere(land) 2)Hydrosphere(water) 3)Biosphere(living things) 4)Atmosphere(air).
Energy and matter flow through Earth's four spheres.Energy flows through the atmosphere and hydrosphere mostly by convection.The continuous cycling of matter and energy through earth's system makes life on earth possible .Others are driven by energy from the sun.
