lämpöalueisiin

Lämpöalueisiin, or thermal zones, refers to the division of the Earth's surface into distinct regions characterized by similar temperature patterns and climate conditions. These zones are primarily determined by the amount of solar radiation received, which is influenced by latitude and the angle at which sunlight strikes the Earth. The tropics, temperate zones, and polar regions are the most widely recognized broad thermal zones.

The tropical zone, located around the equator, receives the most direct sunlight throughout the year, resulting in consistently high temperatures and minimal seasonal variation. This zone is characterized by warm climates and high humidity in many areas. Moving away from the equator, the temperate zones experience more distinct seasonal changes, with noticeable variations between warm summers and cold winters. The amount of solar radiation varies significantly throughout the year due to the Earth's axial tilt.

The polar regions, situated at the Earth's poles, receive the least direct sunlight and experience the most extreme seasonal temperature fluctuations. Winters are long and frigid, with very little daylight, while summers are short and cool, with extended daylight hours. These zones are characterized by icy conditions and very low average temperatures. Understanding these thermal zones is crucial for comprehending global climate patterns, biodiversity distribution, and agricultural suitability across different parts of the world.
