Hazardous Earth Flashcards
What are the names of the 3 circulation cells
Hadely cell, Ferrel cell, Polar cell
60 degrees north and south of the equator and the equator both have ___ pressure and a ____ chance of rainfall and air ____
Low, high, rises
30 degrees N and S of the equator have ___ pressure and ___ rainfall and air ___
high, low, falls
How does altitude change the climate
High-altitude areas have cooler temperatures, more precipitation, strong winds, and low air pressure and oxygen levels. Lower altitude areas have warmer temperatures, little precipitation, less wind, and higher air pressure and oxygen levels.
How does continentality (Distance from the sea) change the climate
In the summer coastal areas are often cooler as the sea has a higher specific heat capacity meaning it takes longer to heat up, however in the winter coastal areas are warmer as the sea takes longer to cool down
How does latitude change the climate
places closer to the Equator are usually warmer, and places nearer to the North Pole and South Pole are colder
How does soil change the climate
Soils that are wetter or denser hold heat and stabilize the surroundings from temperature changes more so than drier, looser soils.
Definition of climate change
a long-term change in weather patterns
What is the greenhouse gas effect
The greenhouse effect is a process that occurs when gases in Earth’s atmosphere trap the Sun’s heat. This process makes Earth much warmer than it would be without an atmosphere.
How do asteroids cause climate change
The dust and aerosols being ejected high into the atmosphere prevent sunlight from reaching the Earth cooling the planet
How do volcanic eruptions cause climate change
Violent volcanic blasts force huge amounts of ash and gases (like sulphur dioxide) into the atmosphere. The blanket of ash and gas stops sunlight reaching the Earth’s surface. Thus cooling the Earth
How do sunspots cause climate change
Ultraviolet radiation increases dramatically during high sunspot activity, which can have a large effect on the Earth’s atmosphere. The converse is true during minimum sunspot activity.
How does the orbital theory (Milankovitch Cycles) cause climate change
Changes to Earth’s climate over long periods are caused by the natural variations in intensity and distribution of solar radiation that reaches the planet
What are the 3 Milankovitch Cycles
The shape of Earth’s orbit, known as eccentricity; The angle Earth’s axis is tilted with respect to Earth’s orbital plane, known as obliquity; and. The direction Earth’s axis of rotation is pointed, known as precession.
How does industry cause climate change
Machines used in the manufacturing process often run on coal, oil, or gas; and some materials, like plastics, are made from chemicals sourced from fossil fuels. The manufacturing industry is one of the largest contributors to greenhouse gas emissions worldwide.
