Among the given options that is given above ''All life was marine (i.e., found in the ocean)'' is true about life in the Precambrian.

Answer: Option D

<u>Explanation:</u>

During the Precamnrian time which includes Earth's history from birth up to 590 million years ago. Precambrian time is further sub divided into Hadean time, Archean time and Paleoproterozoic time, neoproterozoic time.

The sea was mother of all lives and still remains still today. The land based animals also carry a miniature ocean which is present in their cells and circulatory system. All lives including humans could be considered bags of sea water.

describe the factors that control the rate of chemical weathering and those that control the rate of physical weathering
Musya8 [376]
The rate of chemical weathering is controlled by such things as the temperature, the amount of rainfall and the surface area of the minerals which constitute the rocks. Rocks with a finer grain size have more surface area than coarse-grained rocks so are more susceptible to chemical weathering, like a volcanic rock compared to a granite, say. With higher temperatures and greater rainfall, chemical reactions in the rocks are facilitated and this is why, for example argillic (clay alteration) alteration is so well developed in the tropics (in El Salvador for example and also why the lateritic soils develop in countries like Indonesia and can contain economic amounts of nickel for exampl) . A factor which controls the rate of physical weathering could be the development of glaciers which transport rocks in their bed, which shapes these boulders and also scores the rocky surfaces these scrape over as the glacier moves. Alternate freezing and thawing in the spring time in the northern hemisphere can speed up the breakdown of the rock by cracking it or opening up pre-existing joints and faults. 



































































































































































































































































































































































































































































































































































































































































































































































































































































































































































































































































































































































and also the surface area of the minerals being attacked.

Sam is rowing a boat away from a dock. the graph shows the relationship between time and Sam's distance from the dock. evaluate
LiRa [457]

Answer:

D. after 3 minutes, Sam is 40 meters from the dock.

Explanation:

For an input of 3, the function will produce a value of 40. That is in 3 minutes, the boat would have covered a distance of 40meters.

We can solve this problem using the given graph.

We know that this is a distance - time graph. The slope of this graph gives the value of the speed of the boat.

  • From the time - axis, mark point 3 which corresponds to the input given.
  • Trace it up to the point where it coincides with the graph.
  • Then find the distance axis value of the point.
  • Doing this yield 40m

So, in 3 minutes, Sam will row a distance of 40m.
