Why Do Humid Tropical Regions Have Only Small Variations In Temperature Throughout The Year?


Why Do Humid Tropical Regions Have Only Small Variations In Temperature Throughout The Year??

Why do humid tropical regions have only small variations in temperature throughout the year? The location of this climatic region is limited to an area where the solar radiation does not vary significantly. … In the summer the winds blow from the cold oceans and keep the temperatures low.

Why are tropical regions warmer than temperate regions?

The tropics are warmer than temperate regions because the sun’s rays arrive almost perpendicular to regions near the equator. Near the poles the angle of incidence of the sun’s rays spreads them out over a much greater area providing less energy per unit area.

Why and how does the level of carbon dioxide CO2 in the atmosphere affect global temperature quizlet?

As the amount of CO2 in the atmosphere increases a greater portion of radiation is returned to the earth which would have otherwise escaped. This increased energy expresses itself as heat. So increased levels of CO2 in the atmosphere tend to raise the overall surface temperature of the earth.

Which of the following sources is the largest greenhouse gas emission in the US quizlet?

The largest source of greenhouse gas emissions from human activities in the United States is from burning fossil fuels for electricity heat and transportation.

Which broad Koppen climate category is characterized by warm summers and moderate cool winters?

A humid continental climate is a climatic region defined by Russo-German climatologist Wladimir Köppen in 1900 typified by four distinct seasons and large seasonal temperature differences with warm to hot (and often humid) summers and cold (sometimes severely cold in the northern areas) winters.

Why do the tropics not continue to get warmer and warmer every year?

The most likely explanation for the lack of significant warming at the Earth’s surface in the past decade or so is that natural climate cycles—a series of La Niña events and a negative phase of the lesser-known Pacific Decadal Oscillation—caused shifts in ocean circulation patterns that moved some excess heat into the

Why tropical regions are hot?

The tropics are warm all year averaging 25 to 28 degrees Celsius (77 to 82 degrees Fahrenheit). This is because the tropics get more exposure to the sun. Because of all that sun the tropics don’t experience the kind of seasons the rest of the Earth does. … Other areas in the tropics have a drier climate.

Why do levels of carbon dioxide in the atmosphere fall during the summer in the northern hemisphere?

During the day or in spring and summer plants take up more carbon dioxide through photosynthesis than they release through respiration [1] and so concentrations of carbon dioxide in the air decrease.

How does CO2 affect climate quizlet?

The greenhouse effect is caused by the presence of greenhouse gases (CO2 methane and nitrous oxide) in the atmosphere. The heat energy from the Sun is allowed to pass through but it traps the heat energy radiating back from the Earth’s surface. … Carbon dioxide gas dissolves in water to form carbonic acid.

Why does too much carbon dioxide in the atmosphere cause climate quizlet?

when too much carbon dioxide (and other gases) are released they trapped in the atmosphere and cause earth’s temperatures to rise. … Carbon affects abiotic things because fossil fuels release carbon dioxide when burned which causes temperature to rise and ocean levels and temperatures to rise.

Which greenhouse gas is produced only by humans quizlet?

Warming of the Earth that results from greenhouse gases. Carbon dioxide (CO2) is the primary greenhouse gas emitted through human activities. In 2012 CO2 accounted for about 82% of all U.S. greenhouse gas emissions.

What gas stays in the atmosphere the longest?


Major Long-Lived Greenhouse Gases and Their Characteristics
Greenhouse gas Average lifetime in the atmosphere 100-year global warming potential
Methane 12.4 years** 28–36
Nitrous oxide 121 years** 265–298
Fluorinated gases A few weeks to thousands of years Varies (the highest is sulfur hexafluoride at 23 500)

Which factors are causes of short term climate changes?

Many factors both natural and human can cause changes in Earth’s energy balance including:
  • Variations in the sun’s energy reaching Earth.
  • Changes in the reflectivity of Earth’s atmosphere and surface.
  • Changes in the greenhouse effect which affects the amount of heat retained by Earth’s atmosphere.

What causes a humid continental climate?

The main reason for the temperatures of Humid Continental is latitude. Places that are 40 degrees away from the equator are over 2 800 miles from the equator this results in less direct sunlight and less warmth.

Why is the climate near the sea humid?

Sea has a humid climate because of its location near the earth’s surface. Earth’s surface traps heat from the sun and therefore air near the earth’s surface starts becoming hot. … Hot temperature and humidity are directly proportional therefore sea has a humid climate.

What factors explain the locations of Earth’s tropical wet and tropical wet and dry climates?

  • Tropical climates are found at or near the equator. Because warm air rises at the equator there is a lot of rain.
  • Tropical wet climates get rain year round. Tropical rainforests grow in this climate zone.
  • Tropical wet and dry climates have a rainy season and a dry season. The vegetation is largely grass.

Why are the tropics so humid?

As the sun shines strongly on the tropics — particularly on the warm oceans which have an effectively infinite amount of water to evaporate into the air — the overlying atmosphere becomes very humid. … If enough water condenses the cloud droplets can become large enough to fall as rain.

Why is it more humid at the equator?

Oceans form a big portion of the equatorial area and solar irradiance cause to huge amounts of evapotranspiration over these oceans in other hand because warm weather has more humidity capacity thus humidity level in equatorial air is high. … So equatorial regions are most humid part of the word.

Why do the tropics have more precipitation than other locations?

The tropics receive a great amount of direct solar energy which produces more evaporation than higher latitudes. The warm moist air rises condenses into clouds and thunderstorms and falls back to earth as precipitation. More evaporation results in more precipitation.

Why are temperatures relatively uniform throughout the year in the tropics?

The answer comes from the relatively small contrast between land and sea surface temperatures in the tropics. The sun remains relatively close to the equator throughout the year and water retains heat much better than air.

What are three characteristics of humid tropical climates?

Tropical humid climates have distinct locations and abundant animal and plant life.
  • Temperature. Rainforests are warm with temperatures staying around 80 degrees Fahrenheit year-round and fluctuating little during any given month or year. …
  • Precipitation. …
  • Location. …
  • Plants. …
  • Animals.

What are the temperature characteristics of a tropical climate?

Tropical climates are characterized by monthly average temperatures of 18 ℃ (64.4 ℉) or higher year-round and feature hot temperatures. Annual precipitation is often abundant in tropical climates and shows a seasonal rhythm to varying degrees.

Why do levels of carbon dioxide in our atmosphere have seasonal variations?

The amount of CO2 found in the atmosphere varies over the course of a year. Much of this variation happens because of the role of plants in the carbon cycle. … Respiration occurs all the time but dominates during the colder months of the year resulting in higher CO2 levels in the atmosphere during those months.

Why is there less CO2 in the winter?

When air changes from summer to winter the colder temperatures force plants to shed their leaves and ultimately die which also means they are absorbing less CO2.

Why do CO2 concentrations vary less at the South Pole?

At the opposite end of the spectrum at the South Pole (90°S latitude) and other sites in the Southern Hemisphere there is hardly any seasonal variability. These latitudinal differences in fluctuation are the result of photosynthetic activity by plants.

How does concentration of carbon dioxide in the atmosphere affect climate?

Carbon dioxide causes about 20 percent of Earth’s greenhouse effect water vapor accounts for about 50 percent and clouds account for 25 percent. … Likewise when carbon dioxide concentrations rise air temperatures go up and more water vapor evaporates into the atmosphere—which then amplifies greenhouse heating.

Is climate change caused by carbon dioxide?

Evidence that CO2 emissions are the cause of global warming is very robust. Scientists have known since the early 1800s that greenhouse gases in the atmosphere trap heat. Global CO2 emissions from human activity have increased by over 400% since 1950.

How does the concentration of carbon dioxide in the atmosphere affect climate quiz?

Q. How does the concentration of carbon dioxide in the atmosphere affect climate? As carbon dioxide concentration increase temperatures decrease.

Which of the following is the biggest reason that atmospheric greenhouse gas levels have increased in the last 150 years?

Human activities are responsible for almost all of the increase in greenhouse gases in the atmosphere over the last 150 years. The largest source of greenhouse gas emissions from human activities in the United States is from burning fossil fuels for electricity heat and transportation.

What’s wrong with having too much carbon dioxide in our atmosphere quizlet?

Too much CO2 in the atmosphere can lead to GLOBAL WARMING.
