What is an example of a seasonal change?
Seasonal effects
Seasonal changes in precipitation and temperature affect soil moisture, evaporation rates, river flows, lake levels, and snow cover . Leaves fall and plants wither as cold and dry seasons approach. These changes in vegetation affect the type and amount of food available for humans and other organisms.
How seasonal changes affect humans?
Fluctuations in weather during seasonal changes may cause the body to falter in its clock-work routines causing imbalances. Sudden and abrupt changes in temperature can make it difficult for the body to adapt. And this in turn may place extra strains on the body.

How do you realize that the season is changing?
Do you know why seasons change? It’s all in the tilt ! While it may seem that the seasons are caused by the earth’s changing distance from the sun, it’s really due to the tilt of the earth’s axis. This tilt—a 23-degree slant-enables the sun to appear above the horizon for different lengths of time at different seasons.
What is the summer caused by?
The Short Answer:

Why are seasonal changes not abrupt?
Weather changes abruptly from day to day, and there is no basic difficulty in understanding such changes because they involve a “fast” and easily observed part of the climate system (e.g., clouds and precipitation) . ... Two key components of the climate system are oceans and land ice.
