What are the two sources of energy for the Earth system?
What are the two sources of energy for the Earth system?
The earth is a vast, complex system powered by two sources of energy: an internal source (the decay of radioactive elements in the geosphere, which generates geothermal heat) and an external source (the solar radiation received from the Sun); the vast majority of the energy in the earth system comes from the Sun.
What are the 5 Earth systems made of?
The five systems of Earth (geosphere, biosphere, cryosphere, hydrosphere, and atmosphere) interact to produce the environments we are familiar with.
How do the parts of the Earth system interact?
Interactions also occur among the spheres. For example, a change in the atmosphere can cause a change in the hydrosphere, and vice versa. Humans (biosphere) harness energy from the water (hydrosphere) by having it spin turbines (lithosphere) to produce electricity.
What are the two sources of energy for the Earth system quizlet?
the sun (external) and radioactive decay (internal) are the two main sources of energy in the earth system. matter moves through earth systems in cycles such as the nitrogen, carbon, phosphorus, and water cycles. an organized group of related objects or components that interact to create a whole.
What are the two sources of energy for the Earth system the sun and Earth’s interior the sun and lightning the sun and wind the wind and Earth’s interior?
Most of the energy in the Earth system comes from just a few sources: solar energy, gravity, radioactive decay, and the rotation of the Earth. Solar energy drives many surface processes such as winds, currents, the hydrologic cycle, and the overall climate system.
What are the 5 spheres of the atmosphere?
Layers of the atmosphere: troposphere, stratosphere, mesosphere and thermosphere. Earth’s atmosphere has a series of layers, each with its own specific traits. Moving upward from ground level, these layers are named the troposphere, stratosphere, mesosphere, thermosphere and exosphere.
What is core made of?
Unlike the mineral-rich crust and mantle, the core is made almost entirely of metal—specifically, iron and nickel. The shorthand used for the core’s iron-nickel alloys is simply the elements’ chemical symbols—NiFe. Elements that dissolve in iron, called siderophiles, are also found in the core.
How do the four Earth systems interact?
Four spheres are all independent parts of a system. The spheres interact with each other, and a change in one area can cause a change in another. Plants (biosphere) draw water (hydrosphere) and nutrients from the soil and release water vapor into the atmosphere. The biosphere contains all the planet’s living things.
How do Earth subsystems interact with one another?
These spheres are closely connected. For example, many birds (biosphere) fly through the air (atmosphere), while water (hydrosphere) often flows through the soil (lithosphere). In fact, the spheres are so closely connected that a change in one sphere often results in a change in one or more of the other spheres.
