Seasons

In science, seasons are the four periods of the year marked by particular weather patterns and daylight hours. The four seasons are spring, summer, autumn (fall), and winter. These seasons occur due to the tilt of the Earth's axis and its orbit around the sun.

Causes of Seasons

The Earth's axis is tilted at an angle of approximately 23.5 degrees. As the Earth orbits the sun, different parts of the planet receive varying amounts of sunlight, resulting in the changing seasons. When a particular hemisphere is tilted towards the sun, it experiences summer, while the opposite hemisphere experiences winter. As the Earth continues its orbit, the tilt causes the seasons to change.

Effects of Seasons

Each season brings distinct changes in weather, temperature, and daylight hours. For example, summer is characterized by longer daylight hours and warmer temperatures, while winter has shorter days and colder temperatures. Spring and autumn have transitional weather patterns.

Study Guide

Here are some key points to remember about seasons:

• The Earth's axis is tilted at an angle of approximately 23.5 degrees.
• Seasons are caused by the tilt of the Earth's axis and its orbit around the sun.
• The four seasons are spring, summer, autumn (fall), and winter.
• Each season brings distinct changes in weather, temperature, and daylight hours.

Understanding the causes and effects of seasons is an important aspect of Earth science. It helps us comprehend the patterns of weather and climate that affect the world around us.
