Question

What are two examples of the size scale and the time scale in Earth science that are at opposite ends of the spectrum.

Choose one answer for size and one answer for time:
O Spatial scales in Earth science can range from the atomic level to the size of the entre Earh
O Time scales in Earth science can range from the fraction or a second that it takes igtnng to stke to the baons of years ago when the uness was created.
O Spatial scales in Earth science can range from the size of a single rock to large portions of the universe.
O Spatial scales in Earth science can range from the atomic level to large portions of the universe.
O Time scales in Earth science can range from the traction of a second that it takes lightning to strike to the 4.6 bilion years that encompass Earth's entire history.

Answer 1

Answer: Size: Spatial scales in Earth science can range from the atomic level to the size of the entire Earth.

Time: Time scales in Earth science can range from the fraction or a second that it takes lightning to strike to the billions of years ago when the universe was created.

Explanation: We are considering the smallest measurement to the largest on the size scale. The atomic level which is the composition of all matter signifies the smallest end of the spectrum while the earth encapsulates our whole planet. "Large portions of the universe" is not specific and can be anything from a continent to a galaxy.

On the time scale, it takes a fraction of a second for lightning to strike while it has taken billions of years since the big bang, for the universe to form. Scientists estimate this to be between 10 and 20 billion years.
