Answer: 1.3 to 1.1 billion years.
Explanation: The oldest rocks in the New York Bight region are found in surface outcrops throughout the Highlands region. These exposures of Precambrian "basement rock" have been estimated at 1.3 to 1.1 billion years old.
Answer:
Stratigraphy and Biostratigraphy.
Explanation:
Relative dating is a method of determination of age, in which one object or organism is compared with the other object or organism found in the heap of strata. It is a method for determining the relative order of the past events, without stating the absolute age.
Stratigraphy is a branch of geology that studies the relative position of the sediments and rocks in the strata with respect to the geological timescale. Biostratigraphy is the branch of stratigraphy which deals with the relative aging of fossils with respect to the strata in which these are found defining a particular period of geological time scale.
None of the above. It is called an Echocardiogram.
This would be global ecology.
This is because "Global ecology"<span> is the study of the interactions among the Earth's ecosystems, land, atmosphere and oceans. </span>Global ecology<span> is very important because it is used to understand large scale interactions and how they influence the behavior of the entire planet, including the earth's responses to future changes.
Hope this helps. :)</span>
