What is the tilt of Earth's axis and how does it affect seasons?

Back

The tilt of Earth's axis is approximately 23.5 degrees. It causes different parts of Earth to receive varying amounts of sunlight throughout the year, leading to the changing seasons.

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It increases with the speed of the object.

Front

At which position will a falling ball have the greatest kinetic energy?

Back

The ball will have the greatest kinetic energy at the lowest point of its fall, which is position C.

Front

What is weathering in geology?

Back

Weathering is the process by which rocks are broken down by natural forces, including chemical reactions, such as acid rain dissolving certain types of rock.

Front

What are the properties of metals?

Back

Metals are typically good conductors of heat and electricity, malleable, ductile, and have a shiny appearance.

Front

What evidence do fossils provide about Earth's history?

Back

Fossils can show that certain organisms lived in different parts of the world, suggesting that continents were once connected.

Front

What is the significance of the rock cycle?

Back

The rock cycle describes the processes through which rocks change from one type to another, including igneous, sedimentary, and metamorphic rocks.

Front

What is the difference between physical and chemical weathering?

Back

Physical weathering breaks rocks into smaller pieces without changing their chemical composition, while chemical weathering alters the minerals within the rocks.

Front

What is the role of gravity in free fall?

Back

Gravity is the force that pulls objects toward the Earth, causing them to accelerate downward when in free fall.

Front

What is the relationship between potential energy and kinetic energy?

Back

Potential energy is stored energy based on an object's position, while kinetic energy is the energy of motion. As potential energy decreases, kinetic energy increases during a fall.
