Flashcard: Introduction to Earth's Systems

Front

What are the two main sources of energy that drive the cycles on Earth?

Back

Energy from the Sun and heat from Earth's interior.

Front

How does energy from the Sun cause changes to rocks on Earth's surface?

Back

It powers weather that breaks down rocks and moves the pieces.

Front

What conclusion can be drawn from observing a mountain over a lifetime?

Back

The processes that shape landforms happen over a very long time.

Front

What happens when a melting glacier reveals dark land underneath?

Back

The melting would speed up because darker land absorbs more sunlight.

Front

What is the effect of a long-term drought on an aquifer?

Back

The water level in the aquifer will decrease because its source is reduced.

Front

Define 'Earth's systems'.

Back

Earth's systems refer to the interconnected components of the Earth, including the atmosphere, hydrosphere, lithosphere, and biosphere.

Front

What is the water cycle?

Back

The water cycle is the continuous movement of water on, above, and below the surface of the Earth.

Front

What are constructive forces?

Back

Constructive forces are geological processes that build up landforms, such as volcanic eruptions and sediment deposition.

Front

What are destructive forces?

Back

Destructive forces are processes that break down landforms, such as erosion and weathering.

Front

Explain the role of the Sun in Earth's weather systems.

Back

The Sun provides energy that drives weather patterns, influencing temperature, wind, and precipitation.
