What property of detrital sedimentary rocks can be indicative of the energy of sediment transport?

Grain Size

Explanation:

Among the four options given in question statement, the correct option is first one, that is Grain size.

Detrital sedimentary rocks or clastic sedimentary rocks are made up of rock pieces that have been battered from already existing rocks. It is the grain of sediments that stick and combine to ultimately form the rock and the size of the grain determines the energy of sedimentary transport

explanation:

it is very hard for the climatologists to precisely predict how will the global temperatures be changing so there's lots of models, some of which differ significantly, this is due to multiple factors, and probably the most important is the human activity.

humans have been a key factor in climate change around the globe since the start of the industrial revolution, and in the past few decades the consequences are becoming more obvious. there's lots of emission of pollutants in the atmosphere as well as changing the environment on the surface itself, so it's really hard to predict how will that go in the future because there's some countries that are reducing the damage and are going towards green energy, while others are stubbornly continuing with pollution and damages to the environment.
