Spring is the time of year when the natural world is rejuvenated after the cold winter months. New plants start to grow and animals start to wake up during the spring.
The definition of spring is dependent on the sky. The angle of Earth's tilt toward the sun is what defines the spring. Between the spring equinox and the summer solstice is the period known as spring.
Day and night are almost equal during the year. Each year there are two equinoxes, one in the spring and one in the fall. The spring is in the Northern Hemisphere and in the Southern Hemisphere.
Spring is one of two times when the Earth's axis is not pointed toward or away from the sun. During the summer season in the Northern Hemisphere, the North Pole is at its greatest angle to the sun. The South Pole will be closer to the Southern Hemisphere around December 21.

Warming occurs in the hemisphere that is tilted closer to the sun. The ground, which may have been frozen over in the winter, is softer and more yielding to plants. Increased precipitation helps to water the infant seeds taking root in the ground.
The animals that traveled to warmer regions come out of their dens. In the spring, many animals give birth. Some animals may change their color to blend in with their new surroundings, because winter coats are shed by those that wear them.
The rising precipitation of spring may cause flooding as the snow is washed away. The warm air from the equator can combine with the still-cool air farther north or south to make for storms.

The presence of tree buds is one of the first signs of spring. The buds of a plant act as a shield. Different shapes, sizes and forms of flowers are protected.
