Jade described one of the components of weather as follows: It drops as you go higher.
It is usually higher on summer days.
Its low and high are usually shown on weather map.
Which weather component is Jade describing?

Air temperature

Humidity

Precipitation

Wind speed

Air temperature

Explanation:

Air temperature is being described by Jade according the properties highlighted.

The degree of hotness or coldness of a body is known as its temperature.

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.
