Energy Types
What is Energy of Motion called
Kinetic Energy
What is the process called when potential energy is converted to kinetic energy?
Energy Transformation
The sun transfers Energy through
Radiation
Name one way humans impact the water cycle.
Pollution, deforestation, urbanization, etc.
Describe how convection currents are formed.
Convection currents are formed when warm fluid rises and cool fluid sinks, creating a circular motion.
List one type of potential energy
Gravitational Potential Energy, Elastic Potential Energy, Chemical, Radiant, Sound, Light, Nuclear
Describe what occurs to the potential energy as an object falls.
Potential energy decreases while kinetic energy increases.
3 ways heat can be transferred
Conduction, Convection, Radiation
What is one consequence of overusing water from an aquifer?
Lowering the water table or depletion of the aquifer.
What role does uneven heating of the Earth play in convection currents?
Uneven heating creates areas of different temperatures, causing fluids to move and form convection currents.
What happens to the kinetic energy when the speed of an object is doubled?
The kinetic energy increases by four times.
What factor affects kinetic energy more: mass or speed?
Speed
Describe Convection.
Heat transfer through fluids where warmer fluid rises and cooler fluid sinks.
How does climate change affect the water cycle?
It can increase evaporation rates and alter precipitation patterns.
Earths Rotation causes the
Coriolis Effect
In a roller coaster, where is potential energy at its highest?
At the top of the hill
Explain how thermal energy is transferred between two objects in contact.
Conduction
What is Radiation?
Heat transfer through space without the need for a medium.
List two activities that can cause water levels in aquifers to fall.
Excessive water use for agriculture and domestic activities.
How do ocean currents relate to convection patterns?
Ocean currents are large-scale convection patterns that move warm and cold water, affecting climate and weather.
What type of energy is stored in a stretched rubber band?
Elastic Potential Energy
At the bottom of a roller coaster kinetic energy is the
greatest
Give an example of a situation where convection occurs.
Boiling water in a pot.
What is one way to positively impact the water cycle?
Implementing water conservation practices.
How does particle movement relate to convection currents?
As particles move due to heating, they create currents as warmer, less dense particles rise and cooler, denser particles sink.
