In addition to direct measurements , relative sea surface temperatures can be inferred with radar measurements from satellites . Cold sea surface water will be further away from the satellite than warm sea surface water . Explain why this occurs .
Cold water sinks because it is more dense , so it will be further away from the satellite .

) Describe how the results of the study would differ in total rainfall over a six - month period in the southeastern United States if the data were collected during a La Niña year rather than an El Niño year
During La Nina , normal conditions are just intensified . Southeast US tends to be a drier and warmer climate , so rainfall would decrease since La Nina would make the south even drier and warmer
( i ) Explain how a change in the atmosphere that results from El Niño conditions represented in the model would affect Australia
El Niño creates dry conditions in Australia , which means that the continent is now more prone to droughts and fires . Lessened accessibility to water sources means that the plants and animal life may decrease as water becomes scarce
Energy from the Sun drives the Earth's climate and weather . The most intense solar radiation arrives at the equator . Solar radiation leads to the greenhouse effect , which is essential for life on Earth ( a ) There is evidence that global climate change over the past 100 years has led to an increased warming of Earth because of the greenhouse effect . Describe how the solar radiation that arrives at the equator is redistributed around the Earth through atmospheric circulation
Energy from the sun heats up the earth and warms the atmosphere . Heat can then be redistributed by convection currents , which form as a result of unequal heating . Unequal heating also abers redistribute the heat
El Niño and La Niña are natural phenomena associated with changing water temperatures in the Pacific Ocean . The occurrence of these events can result in changes in global weather and ocean circulation patterns
Fewer hurricanes forming in the Central Atlantic basin .
The most abundant nonanthropogenic (not caused by or contributed to by humans) greenhouse gas?
H2O
( ) Identify one human activity that could directly contribute to global climate change
Humans burn large quantities of fossil fuels , which expels lots of carbon dioxide into the atmosphere 002 is a greenhouse gas , so it traps heat in the atmosphere and contributes to global warming
Describe one environmental effect resulting from the conditions represented in the model that could have a negative effect on humans in western South America .
Humans in westem South America experience warm and wet conditions . This means that there is a higher risk of flooding landslides , which decimate residential areas and can take many lives .
Niño and La Niña are natural phenomena associated with changing water temperatures in the Pacific Ocean . The occurrence of these events can result in changes in global weather and ocean circulation patterns .
Increased phytoplankton concentrations
Which of the following correctly characterizes one of Earth's atmospheric layers ?
Layer D is the thermosphere where auroras are found .
Which of the following best explains why the shaded area receives more snowfall than the other parts of New York , Pennsylvania , and Ohio ?
Moisture picked up from the warmer water in the Great Lakes is deposited as snow downwind .
Which of the following is the source of energy driving the circulation pattern labeled C in the diagram ?
Solar radiation
Corn is a crop that grows best in soil that drains well. Which of the following soils is best suited to grow corn?
Sandy loam because it has large amounts of sand and less than 20% clay.
Based on the diagram, which of the following changes are most likely to occur in the central and eastern tropical Pacific during El Niño?
The Peruvian current weakens, leading to warmer-than-average sea-surface temperatures.
If the diagram illustrates Earth's relative position on December 21 of a given year, which of the following statements would be correct?
The Tropic of Cancer has a shorter day and lower solar radiation intensity because there is a direct relationship between length of day and radiation intensity
( ) Describe a change in ocean circulation that results from an El Niño event that is represented in the model .
The currents reverse so that instead of the warm water circulating towards Australia , it now circulates towards South America . This means that the upwelling now occurs near Australia , not South America .
Which of the following best describes acid mine drainage?
The leakage of water containing toxic materials from coal and metal mines
Which of the following causes the air to rise high into the atmosphere in the areas labeled A, B, and C on the diagram above?

Based on the diagram , which of the following identifies a characteristic of the atmosphere between the stratopause and the tropopause ?
The ozone layer is in the stratosphere .
Which of the following best explains why City B regularly receives less precipitation than City A ?
The rain shadow effect causes City B to be drier because the mountain blocks precipitation from reaching the city .
