Question

question 11 2 pts the following data was collected from sites in the atlantic ocean surrounding the mid - atlantic ridge. explain how the data supports the theory of seafloor spreading. be sure to include at least one specific piece of data as evidence. write your answer as complete sentences for full points (capital, period, proper spelling/grammar). copy/paste from the internet or use of ai is an automatic zero. audio recording can also be submitted.

Explanation:

The theory of seafloor spreading posits that new oceanic crust is formed at mid - ocean ridges and moves away from them. The data shows that as the distance from the Mid - Atlantic Ridge increases, the age of the sediments also increases. For example, at site 16 which is 221 km from the ridge, the sediment age is 11 million years, while at site 20 which is 1303 km from the ridge, the sediment age is 67 million years. This indicates that the farther from the ridge, the older the sediments, supporting the idea that the seafloor is spreading away from the ridge over time.

Answer:

The data supports the theory of seafloor spreading because as the distance from the Mid - Atlantic Ridge increases, the age of the sediments increases. For instance, site 16 is 221 km from the ridge with 11 - million - year - old sediments and site 20 is 1303 km from the ridge with 67 - million - year - old sediments, showing that the seafloor is spreading away from the ridge over time.
