1 multiple choice 10 points
how do volcanic eruptions impact the atmosphere?
volcanic eruptions release greenhouse gases such as carbon dioxide into the atmosphere along with ash and dust into the atmosphere.
volcanic eruptions improve air quality in the atmosphere.
volcanic eruptions emit large amounts of oxygen into the atmosphere.
volcanic eruptions decrease the quantity of gases in the atmosphere.

2 multiple choice 10 points
the earths surface is broken into plates that move as a result of
heat distribution within the atmosphere caused by the sun
convection currents within the earths molten interior
earths rotation in space and distance from the sun
water flow around the planet and throughout the geosphere

3 multiple choice 10 points
how does earth work as a system?
no parts of the planet are interconnected or interdependent.
a few parts of the planet are interconnected and interdependent.

Explanation:

Analyze volcanic impacts on the atmosphere

Volcanoes release gases (like \(CO_2\), \(SO_2\), water vapor) and particulate matter (ash, dust) directly into the air. This matches the first option for Question 1.

Analyze the driving force of plate tectonics

Tectonic plates move due to thermal convection currents in the mantle (Earth's molten interior), where hot material rises and cooler material sinks. This matches the second option for Question 2.

Analyze Earth as a system

Earth operates as a complex system where all spheres (geosphere, atmosphere, hydrosphere, biosphere) are interconnected and interdependent. This matches the third option (partially visible but clearly stating interconnectedness) for Question 3.
