Atmosphere 1
Which layer of the atmosphere contains the ozone layer?
Stratosphere
Which layer of the atmosphere contains all weather phenomenon?
Troposphere
Define: Weathering
Weathering is the natural process that breaks down rock into smaller pieces over time.
Define: Erosion
Erosion is the natural process where rock, soil, or sediment is carried from one location to another.
What is deposition?
The laying down of sediment.
List two greenhouse gases.
Carbon dioxide, methane, nitrous oxide, and water vapor.
What is the ozone layer made of?
three atoms of oxygen, O3.
What is the difference between physical weathering and chemical weathering.
Physical weathering breaks down rock without changing the chemical composition while chemical weathering breaks down rock by changing the chemical composition.
List four agents of erosion.
Water, wind, ice and gravity.
List two landforms that are created from deposition.
Sand dunes, beaches, river deltas, and moraines.
What is the importance of the ozone layer?
Protect us from harmful UV sun rays.
What is the role of greenhouse gases?
Traps heat in the Earth's atmosphere.
What is abrasion?
Abrasion refers to the process of wearing away or grinding down or rocks, soil, or other material by the frictional force of particles carried by wind, water, ice, or other agents.
Describe two water sources in which erosion occurs.
Ocean waves, runoff, rivers and streams.
Describe the formation of a river delta?
As sediment moves through a river, the sediment is deposited and collected at the mouth of a river. Over time this sediment accumulates and forms a river delta.
As carbon emissions increase, this can lead to ________________.
Global warming
What is global warming?
The gradual increase of the Earth's temperature.
What is Ice wedging?
Ice wedging is the process in which rocks break down due to water in rocks freezing and expanding.
List two landforms created from ocean wave erosion.
Sea stacks, sea caves, sea arches, and wave cut cliffs
What helps with the formation of moraines?
Glacial movement and deposition.
What can global warming lead to?
Climate change, sea levels rising, melting of polar ice caps, droughts, forest fires, severe weather etc.
List two things humans can do to prevent global warming.
Decrease deforestation, decrease carbon emissions, recycling, reusing materials and products, etc.
List three agents of chemical weathering.
Oxygen, Carbon dioxide, Water, Living organisms, Acid precipitation.
As glaciers flow over land they pick up sediment in a process called _____________________.
Plucking
What force of nature helps with the formation of sand dunes?
Wind
