Heat Transfer
What is the transfer of heat through direct contact?
Conduction?
What type of energy is stored in the nucleus of an atom?
Nuclear Energy
What is the long-term change in Earth's climate patterns called?
Climate Change
What is the greenhouse effect?
the process by which greenhouse gases trap heat in the Earth's atmosphere
What does it mean for an animal to be endangered?
that it is at risk of extinction
How does heat travel in fluids like water and air?
convection
What type of energy is produced by moving objects?
Mechanical Energy
Name one major human activity contributing to climate change.
Burning fossil fuels
Name two major greenhouse gases.
Name one human activity that endangers animals
habitat destruction
What is the transfer of heat through electromagnetic waves?
radiation
What type of energy is associated with heat?
Thermal energy
How does deforestation contribute to climate change?
it reduces the number of trees that absorb carbon dioxide
How does the greenhouse effect keep Earth warm?
that it traps heat from the Sun, preventing it from escaping into space
How does climate change threaten polar bears?
by melting sea ice, which is their primary habitat and how they hunt for food
Give an example of conduction in everyday life.
touching a hot stove
Explain the difference between electrical energy and chemical energy.
electrical energy involves the movement of electrons, while chemical energy is stored in chemical bonds
What is albedo, and how does it affect Earth’s climate?
the measure of how much sunlight a surface reflects, with lower albedo leading to more heat absorption
Explain why too much greenhouse gas can be harmful.
it leads to global warming and disrupts Earth’s climate systems
How can protecting ecosystems help endangered animals?
it ensures their habitat and food sources remain available
Name one real-life example for each type of heat transfer: conduction, convection, and radiation.
Name one example of energy transformation involving chemical energy.
battery converting chemical energy into electrical energy
Describe how melting ice caps can create a feedback loop in climate change.
hat melting ice reduces albedo, causing more heat absorption, which leads to more ice melting
How does human activity increase levels of greenhouse gases?
through activities like burning fossil fuels, industrial processes, and deforestation
Name one example of a conservation effort to protect endangered animals.
creating wildlife reserves or breeding programs
