volcanic eruptions (Runcorn 1962). These can be disastrous in the short-term, but
long-term benefits include the development of new plant life, new habitats, and
better adaptation. The lithosphere also acts as the source of all resources and has
numerous elements, including calcium, aluminum, and copper, that has been used
by humans since the Ancient Egypt period. When the lithosphere and biosphere
interact, organic compounds embedded in the crust can be excavated as natural gas
or oil and used as sources of fuel. The lithosphere, hydrosphere, and atmosphere
combine to provide a crucial source of nutrients that support botanical life, which
produces glucose used by higher organisms for sustenance. Similarly, the biosphere
is an integral part of the Green World since it plays a crucial role in providing water
and air to the planet.
What is the major role of the biosphere? Differentiate between the lithosphere,
atmosphere, hydrosphere, and biosphere. Which of these spheres is the most
important?
2.2 Weather and Climate
Weather is defined as the state of the atmosphere during any specific period; this
includes precipitation levels (rain, snow, and sleet), temperature (warm at 75 ◦ F and
freezing at 0 ◦ F), along with other factors, such as wind and humidity. Weather
is mainly caused by air pressure, moisture, as well as temperature differences in
various locations (Lydolph 1985). On the other hand, climate is defined as the
average weather conditions over a prolonged period. Whereas the weather may
change in only a few hours, climate may take numerous years. Some of the factors
that affect climate are terrain, altitude, latitude, and proximity to water bodies.
How do terrain, altitude, latitude, and proximity to water bodies affect
climate?
James Hansen is among the major contributors to climate and climate change
topics. He directs the Program on Climate Science, Awareness and Solutions,
and is famous for his research in climatology (Hansen 2013). His work helped
raise awareness about climate change encouraging advocacy in avoiding dangerous
climate change. Despite not directly contributing to weather and climate, his work is
influential for highlighting our understanding of climate and climate change trends.
Topography influences snowfall and rain. Mountains particularly play a crucial role
in precipitation patterns. For instance, topographic barriers, like hills and mountains,
