(13 cards)
What are the two key sub-topics of Physical Geography?
Geomorphology and Climatology.
Define Geomorphology.
The study of processes shaping the solid surface and landforms of a planet.
Define Climatology.
The study of processes operating in the atmosphere of a planet.
Name three geomorphic processes.
Erosion, tectonics, volcanism.
Name three atmospheric processes.
Convection, precipitation, atmospheric circulation.
What does it mean when a planet has a differentiated interior?
It has separate core, mantle, and crust layers.
What causes tectonic plate movement on Earth?
Convection currents in the mantle.
What is the largest volcano in the Solar System?
Olympus Mons on Mars.
What is Valles Marineris?
A massive tectonic crack on Mars, not formed by water erosion.
Why are Martian volcanoes so large?
Lack of tectonic plates; volcanoes form over a single hotspot.
What are arachnoids and where are they found?
Spider-web shaped volcanic features found only on Venus.
What is the theory of global resurfacing on Venus?
A rare, cyclical event where the planet’s crust is recycled.
Why is Io the most volcanically active body in the solar system?
Tidal heating from Jupiter’s gravity causes extreme volcanic activity.
