Matter and energy
The sun and the earth's interior are the two sources of energy that power earth's systems.
The sun and the earth's interior are the two sources of energy that power earth's systems.
The two main sources of energy in Earth's system are solar energy, which comes from the Sun, and geothermal energy, which comes from the Earth's internal heat.
Two sources of energy for the Earth system are the sun, which provides solar energy for processes like photosynthesis and weather systems, and the Earth's internal heat, which drives geological processes like plate tectonics and volcanic activity.
The two main energy sources for Earth's system are solar energy from the sun, which drives processes like photosynthesis and weather patterns, and geothermal energy from Earth's internal heat, which powers processes like plate tectonics and volcanic activity.
The Earth system is powered by energy from two major sources: the Sun and the planet's internal heat.
The sun and the earth's interior are the two sources of energy that power earth's systems.
The two main sources of energy in the Earth's system are sunlight, which drives processes through solar radiation, and heat from the Earth's interior, which is generated through radioactive decay and drives plate tectonics, volcanism, and other geologic processes.
Two sources of energy for the Earth system are solar radiation from the Sun, which drives weather patterns, ocean currents, and plant growth through photosynthesis, and geothermal energy from the Earth's internal heat, which powers processes like volcanic activity and plate tectonics.
The sun and the earth's interior are the two sources of energy that power earth's systems.
the sun and the moon
Carbon and Nitrogen were most likely the the first two possible sources of simple organic compounds on earth as a result of exploding stars.
