2 Page. Poster describing some problems our air and climate will experience due to global warming. 2nd page includes an activity.
Carbon is naturally found in the atmosphere. Carbon dioxide, or CO2, itself is not considered a pollutant. The CO2 being released from burning fossil fuels was part of the atmosphere hundreds of millions of years ago before being captured by plants and sea organisms.
A map can represent data from an area on a flat surface. The part of our Earth system most frequently mapped is the atmosphere. Weather—the state of the atmosphere at a particular place and time—needs constant monitoring because it perpetually changes as weather systems evolve and move.
Awareness of what the weather is and is likely to be has numerous benefits. Weather can be hazardous, causing injuries, death, and loss of property. Weather maps are valuable analytical tools for informing people about current or future conditions.
All biological organisms require certain nutrients to live. Plants require carbon, hydrogen, and oxygen from air and water, as well as nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, iron, manganese, copper, zinc, nickel, chloride, boron, and molybdenum from soil. Animals require a few others. Conversions and transformations of nutrients in the environment result from chemical reactions, biological activity, or both.
The ocean is a “carbon sink,” which means that it removes CO2 (carbon dioxide) from the atmosphere. The ocean currently absorbs about one-third of the CO2 released by the burning of fossil fuels.
However, beyond a certain level of atmospheric CO2, the ocean can no longer act as a carbon sink without it having a negative impact on marine life. When CO2 dissolves in seawater, it leads to decreased pH levels. The ocean becomes less alkaline. This is referred to as ocean acidification.
Water moves from Earth’s surface to the atmosphere and then returns to the surface. This process is nearly always depicted in water cycle diagrams by arrows drawn in a circular direction.
However, the actual path water may take in its cycle is far more complicated. In this activity, you will discover multiple cycles by acting as water molecules and traveling through parts of the overall water cycle. In the end, your water cycle will look nothing like the conceptual model but will represent a more realistic cycle.
