Which type of rock is formed when magma cools and solidifies below Earth's surface?
Answer: Intrusive igneous
Intrusive igneous rocks form when magma solidifies slowly beneath Earth's surface, producing coarse-grained rocks like granite.
During the water cycle, what process converts liquid water into water vapor?
Answer: Evaporation
Evaporation is the process by which liquid water absorbs heat energy and transforms into water vapor at the surface.
Which layer of Earth is responsible for the movement of tectonic plates?
Answer: Asthenosphere
The asthenosphere is a semi-fluid layer of the upper mantle that flows slowly, driving the movement of tectonic plates above it.
What is the primary source of energy that drives the water cycle?
Answer: Solar energy
Solar energy from the Sun powers evaporation, which is the first step in the water cycle.
When two oceanic tectonic plates converge, what typically occurs?
Answer: One plate subducts beneath the other
When two oceanic plates converge, the denser plate subducts under the less dense plate, often forming deep ocean trenches.
Which process in the carbon cycle involves plants absorbing CO₂ from the atmosphere?
Answer: Photosynthesis
Photosynthesis allows plants to absorb carbon dioxide from the atmosphere and convert it into organic compounds using sunlight.
What type of boundary is formed where two tectonic plates move apart from each other?
Answer: Divergent boundary
Divergent boundaries occur where plates move apart, allowing magma to rise and form new crust, such as at mid-ocean ridges.
