The correct option is this: VARIATIONS ARE GREATER OVER LAND THAN OVER WATER.
Temperature variation over water is very small compared to temperature variation over land. This is because, water has high specific heat capacity, which enables it to resist temperature changes when it absorb heat or when it releases heat. A large amount of heat has to be lost or gained before water will show a one degree Celsius temperature change.
That would be Artificial Selection.
Answer: A closed circulatory system and an excretory system consisting of tubular nephridia
Explanation:
Answer:
Physical Change:
- Boiling water
- Breaking a pencil
- Water evaporating
- Denting a car door in an accident
- Tearing paper
- Ice melting
- dissolving
Chemical Change:
- Something rusting
- photosynthesis
- metabolism/digestion
- Nuclear power [atoms are arranged differently]
- Smashing paper with two metal balls, burns paper
- Electricity in water, breaks H2O into H2 and O2
-----
physical change is when there is only physical change occurring--and it can typically be undone easily,
whereas chemical change is when there is chemical change--which changes the chemical properties of something, which cannot be undone simply.
hope this helps!!
