* Geotropism: This is a biological phenomenon where a plant grows in response to gravity. It's commonly known as gravitropism. Plants have a "downward" geotropism for their roots and an "upward" geotropism for their stems.
* Geothermal: This refers to the heat within the Earth's interior. It's often used in terms like "geothermal energy," which is harnessed from this internal heat.
* Geodesy: This is the scientific study of the Earth's shape, size, and gravity field. It's a field that uses sophisticated measurements and calculations to understand our planet's structure and dynamics.
Please clarify what you meant by "geotroph" and I can provide a more specific answer.
