Electricity
What is the unit of electric current?
ampere (A)
What is plate tectonics?
Plate tectonics is the scientific theory that Earth's lithosphere is divided into large plates that move slowly across the Earth's surface.
What is the primary way water enters the atmosphere?
Water enters the atmosphere primarily through evaporation where liquid water turns into water vapor due to heat from the sun.
What is Earth's position in the solar system?
Earth is the third planet from the Sun.
What is a star?
A star is a massive, luminous ball of plasma that generates light and heat through nuclear fusion in its core like our Sun.
What is Ohm's Law?
The law that states the current V=l * R
what are the three main types of plate boundaries?
Divergent boundaries convergent boundaries transform boundaries
What is the role of the atmosphere in the water cycle?
The atmosphere acts as a pathway for water movement around the globe transporting water vapor through air currents.
What makes Earth unique compared to other planets?
Earth is the only known planet to support life.
What is a galaxy?
A galaxy is a vast collection of stars gas and dust held together by gravity.
what is the difference between (AC) (DC)?
DC flows in one direction while AC changes direction
What is the process of subduction?
Subduction is when a denser oceanic plate sinks beneath a less dense continental plate at a convergent boundary.
What is the term for water vapor in the atmosphere?
Water vapor is the term used to describe water in its gaseous state present in the atmosphere.
What is the shape of Earth?
Earth is not a perfect sphere
What galaxy do we live in?
We live in the Milky Way galaxy
How does a circuit work?
complete pathway for electricity to flow
How does the movement of tectonic plates cause earthquakes?
When plates interact at their boundaries.
How do plants contribute to the water cycle?
Plants contribute to the water cycle through transpiration where water absorbed by the roots evaporates from the leaves as water vapor into the atmosphere.
How does Earth experience day and night?
Earth rotates on its axis.
How are stars formed?
Stars form when large clouds of gas and dust in space collapse under their own gravity.
what is electricity?
the flow of electric charge
What evidence supports the theory of plate tectonics?
Evidence includes the matching coastlines of continents fossil distribution across continents.
What is the relationship between temperature and the amount of water vapor the atmosphere can hold?
Warmer air can hold more water vapor than colder air.
What is the primary component of Earth's atmosphere that supports life?
Oxygen is the primary component of Earth's atmosphere that supports life.
What are the different types of galaxies?
