All trees will drop their older leaves as the plant grow. It's a matter of time. Some will drop their leaves in response to the environment, eg winter. And this is called deciduous. This is a very common phenomenon in the temperate region. What u see the green part of coniferous is not leaves, but modified stems and branches.
In tropical areas, plants will drop their older leaves continuously from time to time and being replaced by new shoots simultaneously. This type of plants are called evergreen
Occasionally in the tropics, when the weather is too dry for too long (say around 2 months without rainfall, which is not very common in the tropics), the plants will drop all their leaves at the same time, just like during autumn in temperate ares. This is a mechanism for the plant to prevent too much water lost from their system.

I wouldn't say that it is very scientific, but the term used is evergreen. Evergreens are trees that retain their needles year round ie. Norway spruce and White pine.

They are known as evergreen plants, in contrast to deciduous plants (that do loose their leaves).
