Interactions between the spheres

The four spheres of Earth are closely connected to each other. Birds(biosphere) fly through the air (atmosphere), and water (hydrosphere) flows through the soil (lithosphere or geosphere). The spheres of the earth are closely connected to each other. A change in one sphere results in a change in two or more spheres.

Hydrosphere and Atmosphere

• evaporation that occurs in the hydrosphere forms the medium for cloud and rain formation in the atmosphere

• atmosphere brings back this water to the hydrosphere in the form of rain

Hydrosphere and Geosphere

• Hydrosphere provides the necessary moisture required to weather and erode rocks in the geosphere

• geosphere, in turn, allows the ice to melt and the water bodies to flow back into the oceans

Atmosphere and Geosphere

• atmosphere provides the required heat and energy for the breakdown and erosion of rock in the geosphere

• geosphere, in turn, reflects the sun’s energy to the atmosphere

Biosphere and Hydrosphere, Atmosphere and Geosphere

• biosphere receives sunlight and gases from the atmosphere

• It collects water from the hydrosphere and a living medium from the geosphere

• the soil may contain minerals from the geosphere

• moisture within the soil from the hydrosphere

• insects and plants from the biosphere inhabiting the soil and pockets of air present between the soil pieces

If the spheres of Earth stopped interacting with each other:

• the weather would cease with no water cycle

• as a result, plants and trees would not grow without water

• animals could not breathe without oxygen

• surface ocean currents would stop moving without wind

Human Interactions:

• piling up human waste in landfills affects the GEOSPHERE

• polluting the oceans affects the HYDROSPHERE

• over fishing and habitat destructions affect the BIOSPHERE

• burning fossil fuels releases greenhouse gases into the ATMOSPHERE
