Answer:
I believe the answer is C
Explanation:
The answer is option B. The number of protons
If two atoms are isotopes of the same element then the number of protons in those two atoms must be same but the number of neutrons must not be same. If number of neutrons of an atom vary but number of protons in them are same then it simply means that they both are isotopes of a particular element. As we know that every atom has a nucleus which has protons and neutrons and due to these protons and neutrons an atom has weight. Apart from that, an atom has electrons too but they are outside the nucleus. Electrons are extremely light in weight so they do not contribute towards weight but they have a great role in chemical reactions. During chemical reactions, it is electron which directly participates, while proton and neutrons do not take part or move during chemical reactions. Also, in a neutral atom number of protons is equal to number of electrons but when an atom becomes negatively or positively charged, it can gain or loose electrons so electrons have tendency to vary. That is why we cannot consider electrons to be always same for isotopes of an element. It is clear that for an isotope, the number of electrons and neutrons will vary but the number of protons will always be fixed.
Answer:
Weather observations become climate data when weather conditions are measured at thousands of locations every day for 30 or more years.
Explanation:
According to the definition of climate, observations of the weather conditions are required for a very long period of time, even 30 years or more, registered in many places.
Weather refers to the presence of certain characteristics such as air pressure, temperature, humidity or wind speed in a given place in short periods, such as 24 hours.
Meteorologists refer to the climate taking into account the information collected from characteristics, such as temperature, air pressure or rain, in many places and for long periods of time, establishing an average value and with the possibility that this helps to predict weather behavior.
All weather information collected around the world over a period of 30 years or more becomes average values of temperature, air pressure, humidity, speed and wind direction that serve as climate data to predict the behavior of the weather in a determined place.
