Explanation
The puzzle is based on geological processes and heat transfer mechanisms that govern Earth’s dynamics. Each clue represents a fundamental principle in Earth science or physics.
Conduction refers to heat transfer through direct contact between molecules. Air molecules absorb warmth when they interact with hotter surfaces or materials, making conduction the correct answer.
Pangaea was a supercontinent that existed hundreds of millions of years ago. Earth’s crust is composed of fragmented landmasses that were once connected, forming Pangaea.
Convection describes the rising and falling movement of mantle materials. This mechanism helps distribute heat inside Earth, leading to plate movements and geological changes.
A collision occurs when two tectonic plates push against each other. This process can lead to mountain formation or subduction zones where one plate moves beneath another.
Earthquakes result from the shifting or movement of Earth’s tectonic plates. When stress builds up along fault lines, a sudden release of energy causes the ground to shake.
Radioactive elements, such as uranium and thorium, contribute to Earth’s internal heat through radioactive decay, making them crucial for maintaining geothermal processes.
Radiation is the least significant mode of heat transport within Earth because solids and liquids conduct and convect heat more efficiently than radiative transfer.
Sinks describes the behavior of cooler mantle materials. As warm materials rise, cooler ones move downward, maintaining a cycle that drives convection currents.
Magma forms beneath Earth’s crust due to heat accumulation. It consists of molten rock that can lead to volcanic activity when it rises to the surface.
This crossword is a great way to reinforce knowledge about Earth’s dynamic processes. Let me know if you’d like further clarification on any of the concepts.
