All Flashcards
What drives plate movement?
The molten core of the Earth.
Why is soil important?
It's the foundation of terrestrial life, providing nutrients and support for plants.
What is the role of the ozone layer?
It absorbs harmful UV radiation from the sun.
How does latitude affect climate?
Closer to the equator = more direct sunlight = warmer temperatures.
What causes Earth's seasons?
The tilt of Earth's axis.
What is a rain shadow?
A dry area on the leeward side of a mountain range.
Why are greenhouse gases important?
They trap heat in the atmosphere, regulating Earth's temperature. However, too much can cause global warming.
What is the significance of the A horizon?
It is the topsoil layer, rich in nutrients and essential for plant growth.
What is the impact of CFCs on the stratosphere?
CFCs deplete the ozone layer, leading to increased UV radiation reaching the Earth's surface.
How do El Niño and La Niña affect global weather?
They cause shifts in temperature and precipitation patterns, leading to floods in some areas and droughts in others.
What is the effect of CFCs on the stratosphere?
Depletion of the ozone layer, increased UV radiation.
What is the effect of increased greenhouse gases in the troposphere?
Global warming and climate change.
What is the effect of El Niño on global weather?
Floods in some areas, droughts in others.
What is the effect of La Niña on global weather?
Can lead to increased hurricane activity in the Atlantic.
What is the effect of agriculture on soil?
Can lead to soil erosion and nutrient depletion.
What is the effect of mountains on precipitation?
Rain shadows, creating dry regions on the leeward side.
What are the steps of soil formation?
Weathering, erosion, deposition, decomposition.
List the layers of the atmosphere (inner to outer).
Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere
