What does they mean?

[Lê Thiên Hoàng]

No theorist today would deny that the plates do move. Satellites anchored in space record the minute movement of fixed sites on Earth.(the volcano)

I don't understand this sentence.

Which words do you not understand?

There is no "they" in your post.

 

[Lê Thiên Hoàng]

Yes, that's right.

 

[Lê Thiên Hoàng]

sorry, I made mistake. "they" mean " sentence.

Satellites anchored in space record the minute movement of fixed sites on Earth

 

[MikeNewYork]

A sentence would be an "it", not a "they".

 

[Tarheel]

Clearly, the satellites are not anchored in space. And you provide no context for the sentence. Nevertheless, I think it is about tectonic plates.

 

[Matthew Wai]

Lê Thiên Hoàng, do you understand 'Satellites record the minute movement of fixed sites on Earth'?

I don't understand this sentence.

Satellites record the movement of volcanoes - the fixed sites on Earth.
The satellites are anchored in space.
The movements are minute (small).

I think satellites orbit the Earth instead of being anchored in space.

 

[Raymott]

I think satellites orbit the Earth instead of being anchored in space.

Yes, they would, but that's not the meaning of the sentence. The sentence is factually incorrect. That's the OP's problem though.

Lê Thiên Hoàng, please note that a better thread title would have been 'Satellites anchored in space record the minute movement of fixed sites on Earth'.

Perhaps we can help disabuse the OP.

Perhaps we can help disabuse the OP.

Well, I think you possibly have.

You can have geostationary orbit, though, so that the satellite moves as the earth rotates and appears to be fixed in place. It's not a factually accurate way to describe it, but as a metaphor, it works in that the satellite appears to be anchored to the one spot.

I think the problem came from reading "minute" as "60 seconds" ("min'nit") instead of "very small" (my-nute').

The satellites are not anchored in space. They are not attached to anything. (They are in fixed orbit, but that's not the same as being anchored.) Those satellites record the movement of what are otherwise regarded as fixed sites on earth.
