An urban heat island is a phenomenon that is best described when a city experiences much warmer temperatures than in nearby rural areas. The sun’s heat and light reach the city and the country in the same way. The difference in temperature between urban and less-developed rural areas has to do with how well the surfaces in each environment absorb and hold heat.
Students explore the spatial patterns observed in meteorological data and learn how this information is used to predict weather and understand climate behavior.
In this lesson, students will explore the effect of aerosols on sky color and visibility by using an interactive virtual model.
Our Earth is a dynamic system with diverse subsystems that interact in complex ways. Questions that scientists have about the Earth as a System may include the following. As you learn more about the Earth System, reflect on these questions.
In this lesson, students will explore the effect of aerosols on sky color and visibility by using an interactive virtual model.
Students analyze a graph that illustrates the change in global surface temperature relative to 1951-1980 average temperatures.
