Electricity
What is Electricity?
Electricity is the flow of electrical power or charge.
What is the lithosphere?
The rigid outer layer of the Earth, including the crust and upper mantle, which is broken into tectonic plates.
What is the primary gas that makes up Earth's atmosphere?
Nitrogen.
What is Earth's position in the solar system?
Earth is the third planet from the Sun.
What is a star?
A massive, luminous ball of plasma that generates light and heat through nuclear fusion at its core.
List 2-4 device using electric?
a television, a refrigerator, a microwave, and a computer.
What is the asthenosphere?
The partially molten layer of the upper mantle below the lithosphere, allowing the plates to move.
Which layer of the atmosphere is where most weather occurs?
Troposphere.
What is the largest ocean on Earth?
The Pacific Ocean.
What is a galaxy?
A vast collection of stars, gas, dust, and dark matter held together by gravity, containing billions of stars and often appearing as a distinct structure in the night sky.
How many volts do households usually use?
in the United States, we use 110-120 voltages (60 Hz)
Who is credited with the theory of continental drift?
Alfred Wegener.
What is the term for water in its gaseous state in the atmosphere?
Water vapor.
What is the primary gas in Earth's atmosphere?
Nitrogen.
What is our galaxy called?
The Milky Way.
What is electric current?
The flow of charged particles, like electrons, through a conductor
Where does new oceanic crust form?
At divergent plate boundaries, like mid-ocean ridges.
What process causes water vapor to condense into clouds?
Cooling of the air.
What is the name of the layer of the atmosphere where most weather occurs?
Troposphere.
What is the closest star to Earth?
The Sun.
What are some basic electrical concepts?
Voltage, current, resistance, Ohm's law, Kirchhoff's Current Law (KCL), and Kirchhoff's Voltage Law (KVL)
What is a transform boundary?
A plate boundary where plates slide past each other horizontally, often causing earthquakes.
Explain the water cycle in detail, including the stages of evaporation, condensation, precipitation, and collection.
Water evaporates from bodies of water, rises in the atmosphere, condenses to form clouds, falls as precipitation, and collects back on the Earth's surface.
What is the greenhouse effect?
The trapping of heat by gases in the atmosphere, like carbon dioxide.
What is the main fuel that powers a star?
Hydrogen.
