A system that receives energy from external sources is called?
open system
Energy can enter the earth system from internal sources through convection and from external sources through what?
External sources of energy entering the Earth system include solar radiation and cosmic rays. Solar radiation, the primary external energy source, drives various processes and is essential for sustaining life on Earth. Cosmic rays, though less significant than solar radiation, also contribute to the energy balance of the planet.
What does external energy mean?
External energy refers to energy that comes from sources outside of a system. This energy can be transferred to or from the system, impacting its overall energy level or ability to perform work. Examples of external energy sources include mechanical work applied to a system or heat transferred to or from the system.
How can you can increase or decrease the energy possessed by electrons?
To increase the energy possessed by electrons, you can provide them with external energy sources such as heat or light. This can excite the electrons to higher energy levels. To decrease their energy, you can remove external energy sources, causing the electrons to lose energy and move to lower energy levels.
How can one build a perpetual motion machine that can generate unlimited energy without the need for external sources of power?
It is currently not possible to build a perpetual motion machine that can generate unlimited energy without external sources of power. The laws of physics, specifically the law of conservation of energy, dictate that perpetual motion machines are not feasible.

How are heterotrophs and autotrophs similar in their dependence on external sources for energy and nutrients?
Heterotrophs and autotrophs both rely on external sources for energy and nutrients. Heterotrophs obtain these from consuming other organisms, while autotrophs produce their own energy through processes like photosynthesis. Both types of organisms need external sources to survive and function.

Energy sources other than fossil fuel are called what kind of resources?
They are called renewables. (though strictly, nuclear power is not a fossil fuel and is not renewable).They are called alternative energy sources.
Does earth have radioactive internal energy and external energy?
Yes, Earth does have radioactive internal energy, which comes from the decay of radioactive elements in its core. As for external energy, Earth receives energy from the Sun in the form of solar radiation, which affects various processes on the planet such as weather patterns and climate.
Energy sources replaced through ongoing natural processes are called?
natural energy sources
Describe the Earths principal sources of internal and external energy?
The Earth's principal sources of internal energy are radioactive decay of elements in the Earth's core and residual heat from the planet's formation. External energy sources include solar radiation, which drives processes like weather patterns, ocean currents, and ecosystems. Together, these energy sources contribute to the dynamic processes shaping Earth's geology and climate.

It is currently not possible to build a perpetual motion machine that can generate unlimited energy without external sources of power. The laws of physics, specifically the law of conservation of energy, dictate that perpetual motion machines are not feasible.
What are energy sources other than fossil fuel called?
Re-newable
Is the energy acquired by a body because of its motion is called potential energy?
No, energy created from movement is called Kineticenergy. Potential energy is energy created from no moving sources.
