July 2018 was the driest July in Australia since 2002. The dry month exacerbated an ongoing drought that had already ruined large swaths of grazing land and cropland.
In this activity, students explore three indicators of drought are: soil moisture, lack of precipitation, and decreased streamflows. Students investigate each of these parameters develop a sense for the effects of drought on land.
Three-dimensional measurements of the central Brazilian Amazon rainforest have given NASA researchers a detailed window into the high number of branch falls and tree mortality that occur in response to drought conditions.
Please consider using this graphic organizer to help students analyze the processes and components of Earth System phenomena.
Soil moisture is the water that is held in the spaces between soil particles, generally in the upper 10 cm of soil. Although soil moisture is just a fraction of the total water mass in the water cycle, this small amount of water plays a critical role in evaporation and plant transpiration proces
Helping students build their understanding of Earth's spheres and how they are connected is difficult. Review the graphics below to help identify the parts of the Earth System and the processes that connect them at the local, regional, and global scales.
Earth-orbiting satellites and other technological advances have enabled scientists to observe changing atmospheric temperatures as they collect many different types of information about our planet and its climate on a global scale.
Students will examine a 2014-2015 El Nino Southern Oscillation (ENSO) event to identify relationships among sea surface height, sea surface temperature, precipitation, and wind vectors.
