Analyze Earth system interactions

The first question asks which statement is true regarding Earth's systems. Earth's spheres (atmosphere, biosphere, geosphere, and hydrosphere) are deeply interconnected. Water in the hydrosphere evaporates into the atmosphere, sustains life in the biosphere, and shapes landforms in the geosphere. Therefore, the hydrosphere interacts with all other spheres.
Using the Earth Systems knowledge point, we confirm that spheres do not operate in isolation.

Define the geosphere structure

The second question asks for the correct definition of the geosphere. The geosphere refers to the solid, non-living parts of the Earth. This includes the crust (both continental and oceanic), the mantle, the core, and surface landforms like mountains and rocks. It excludes gaseous components (atmosphere) and liquid water bodies (hydrosphere).

Evaluate rock cycle relationships

The third question asks which relationship in the rock cycle is correct. Sedimentary rocks are formed by the accumulation, compaction, and cementation of mineral and organic particles (sediment) on Earth's surface. Igneous rocks form from cooling magma or lava, while metamorphic rocks form from existing rocks subjected to intense heat and pressure.

Determine the driver of plate tectonics

The fourth question asks about the cause of convection currents driving plate tectonics. Convection currents in the mantle are driven by the transfer of heat from Earth's hot interior (core and deep mantle) to the cooler upper mantle.
Using the Plate Tectonics knowledge point, we identify Earth's interior heat as the primary energy source driving this motion.
