How do the biosphere and hydrosphere interact? sākt mācīties
|
|
The biosphere and the hydrosphere have two different definitions, but their domains overlap. The biosphere includes all life on Earth. This includes humans and other life on land. But it also includes aquatic life, which lives in the hydrosphere. However, some parts of the hydrosphere are not part of the biosphere. This includes water stored in the upper atmosphere.

What are some features of the Earth's orbit around the sun? sākt mācīties
|
|
The Earth revolves around the sun, following an elliptical orbit. Since the path is not a perfect circle, the Earth's distance from the sun varies throughout the year. That is why a year is 365 days, with one extra full day every four years to account for the extra 0.25. However, these variations are too small to affect the seasons. The Earth makes one full revolution once every 365.25 days.
|
|
|
How do the Earth's movements affect conditions on the surface? sākt mācīties
|
|
The conditions on the surface of the Earth change depending on the position of the Earth in relation to the sun. As the Earth revolves, it remains at a fixed tilt. for half of the year and tilted away for the other half. This causes the changing seasons throughout the year. Of course, the conditions also change each day as the Earth rotates. The 24-hour rotation causes alternating days and nights. As a result, each pole is tilted towards the sun
