Have you heard about geosynchronous satellites?

Yeah, they stay in the same position relative to the Earth, right?

Exactly! It’s fascinating how they orbit at the same speed as the Earth's rotation.

I know! It really helps with communication and weather monitoring.

Root Explanation

Geosynchronous → It is formed from "geo-" (from Greek "geō", meaning earth) and "synchronous" (from Greek "synchronos", meaning occurring at the same time). The word describes an orbit that matches the Earth's rotation, thus occurring at the same time as the Earth.

Memory Tip

Think of 'geo-' meaning earth and 'synchronous' meaning at the same time — this helps you remember that geosynchronous refers to something that stays in sync with the Earth's rotation.
