Analyze geoscience data to make the claim that one change to Earth's surface can create feedbacks that cause changes to other Earth systems.
Scientists collect data to understand Earth and how it changes. Quantitative data involves taking measurements, while qualitative data are observations and descriptions of phenomena. When it comes to climate, scientists try to collect as much and as many types of data as possible to be able to analyze how climate is changing and what effects it is having. Because climate affects all areas of the world, collecting this data is a large undertaking. This is where you can help.
Soil erosion is the process of moving soil by water or wind — this happens naturally or through human interference. Preventing soil erosion is important because nutrients are lost, and sediment that accumulates in waterways impacts life there. Conserving soil depends on how it is protected by plants and coverings.
You will model erosion by water and compare the amounts of runoff and soil loss generated from three different ground cover types.
On our ever-changing Earth, conditions may change quickly or slowly. Some changes come from natural processes; some from human activity. Satellites allow us to see conditions and track changes over time — in land use, forest health, land/water interface, and so on. Since 1972, Landsat satellites have been collecting data using various portions of the visible and invisible electromagnetic spectrum, at a scale close enough to see highways, but not individual buildings on a city block.
Soil is a vital component of almost every ecosystem, and its health often determines the viability of the whole ecosystem. If a soil cannot support the living organisms within it – such as insects, bacteria, fungi, and plant roots – then it is likely that the entire ecosystem will suffer. The same is true on farms. The success of crops is dependent on the health of the soil.
