The earth has gone through warming and cooling phases in the past, long before humans were around. Forces that can contribute to climate change include the sun’s intensity, volcanic eruptions, and changes in naturally occurring greenhouse gas concentrations.
What causes long-term change in climate?
Carbon dioxide is the main cause of human-induced climate change. … Some, such as nitrous oxide, are long-lived greenhouse gases like carbon dioxide, and so contribute to long-term climate change. Other substances have shorter atmospheric lifetimes because they are removed fairly quickly from the atmosphere.
What are 3 factors that affect long-term climate cycles?
Factors Affecting Global Climate
- Atmospheric Circulation. The sun’s rays provide both light and heat to Earth, and regions that receive greater exposure warm to a greater extent. …
- Ocean Currents. …
- Global Climate. …
What are two long-term physical impacts of climate change?
Rising Sea Levels
Warmer climates cause sea levels to rise by two mechanisms: 1) melting glaciers and ice sheets (ice on land) add water to the oceans and 2) ocean water expands as it warms, increasing its volume and raising the sea level.
What are some natural and human factors that impact climate change?
Humans are increasingly influencing the climate and the earth’s temperature by burning fossil fuels, cutting down forests and farming livestock. This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming.
Which is a natural factor that causes long-term climate change quizlet?
Geographic changes in Earth’s land and water bodies can cause changes in climate. Changes in the shape of Earth’s orbit and the tilt of the Earth on its axis can also affect global climates.
What are the 6 major factors that affect climate?
LOWERN is an acronym for 6 factors that affect climate.
- Latitude. It depends on how close or how far it is to the equator. …
- Ocean currents. Certain ocean currents have different temperatures. …
- Wind and air masses. Heated ground causes air to rise which results in lower air pressure. …
- Elevation. …
What is long term climate change?
Climate change is the long-term alteration of temperature and typical weather patterns in a place. … Together with expanding ocean waters due to rising temperatures, the resulting rise in sea level has begun to damage coastlines as a result of increased flooding and erosion.
Which two factors have the greatest effect on climate?
The two most important factors in the climate of an area are temperature and precipitation. The yearly average temperature of the area is obviously important, but the yearly range in temperature is also important.
What is a long term environmental change?
Long Term Changes
A long-term environmental change is… ice age, deforestation, urbanization, Earth’s orbit, Sun’s intensity, global Warming, radioactive waste/pollution. Extinction of species could happen to anyone of the food webs in a long term change.
What is natural climate change?
Anthropogenic climate change is defined by the human impact on Earth’s climate while natural climate change are the natural climate cycles that have been and continue to occur throughout Earth’s history.
Which effects are factors in long term climate change quizlet?
Changing orbit of earth, stretch, tilt and wobble can cause long term climate change. Volcanic activity emitting ash and dust particles into the atmosphere which block incoming solar radiation. The eruptions can also release gases into the atmosphere (carbon dioxide and sulphur dioxides increasing % of GHGs).
What are the 5 causes of climate change?
The National found out the five main culprits for this increase in greenhouse gases.
- Fossil fuels. Expand Autoplay. …
- Deforestation. …
- Increasing livestock farming. …
- Fertilisers containing nitrogen. …
- Fluorinated gases.
