This document discusses interactions between different Earth systems. It describes how volcanoes erupt, sending ash and gases into the atmosphere and lava and ash onto surrounding land and human settlements. It also describes how hurricanes sweep across oceans and onto coasts, damaging structures, and how earthquakes can damage buildings, cause fires, and trigger tsunamis, all affecting the geosphere, atmosphere, biosphere, and hydrosphere. The document also notes how human activities like altering albedo, burning fossil fuels, and damming rivers impact Earth's climate and water cycle.

10. System Interactions
Earthquakes can damage buildings which
may kill people, as well as cause fires which
release gases into the air. Earthquakes in
the ocean may cause a tsunami which can
eventually hit land and kill both animals
and people.

11. • Humans can alter the albedo of an area,
which affects the Earth’s energy budget
• We can burn fossil fuels which puts
CO2 in the air, or plant trees, which
takes CO2 out of the air
• Damming a river lengthens the amount
of time it takes water to go through the
water cycle
