Which statement best explains why Earth's lithosphere is broken into tectonic plates?
Nadusha1986 [10]

Answer:

( d ) The brittle lithosphere cracks under pressure from the moving asthenosphere.

Explanation:

~ The earth's crust refers to the outer layer of the planet earth . The surface of a planet is usually formed of less dense material than the deeper layers. Only 1/3 of the earth's crust is terrestrial , the rest is covered by oceans . The thickness of the earth's crust is between 10 to 30 miles.

The earth's crust, which is the upper part of the lithosphere , is divided into two layers. The top layer is continental , which is composed of granite . While under granite is a layer of hard rock called basalt .

On a semi-liquid planet , such as Earth , the earth's surface floats on top of the liquid inner layer. The crust seems to be often divided into pieces known as tectonic plates which due to the movement of molten magma beneath it, are able to move. This is a phenomenon of continental drift theory . In addition, collisions between two tectonic plates can produce volcanoes .

The Earth's crust is made up of rocks, minerals, soil and fossil fuels.

The toxic condition characterized by retention of nitrogenous substances in the blood is called:
RideAnS [48]

The toxic condition characterized by retention of nitrogenous substances in the blood is called uremia.  Uremia is a toxic condition caused by retention in the blood of nitrogenous waste products normally excreted in the urine.  Acute renal failure denotes a sudden onset of renal failure, such as that caused by an accident, certain drugs or poison. The kidneys may recover or the damage may be permanent. If the kidneys stop functioning this condition is what they called uremia, therefore the body is full of  extra water and waste products, leading to swelling in the hands or feet, fatigue and weakness. End-stage renal disease refers to when the kidneys have lost all or nearly all function.

Answer:

2, 4, and 5 refers to scientific revolution while on the other hand, the remaining statements shows scientific observation.

Explanation:

Cloning has the potential to  significantly benefit a great many  people, so it should not be  considered immoral or risky is refers as scientific observation.

A scientist thinks that he might  find serious inconsistencies in the  fossil record if he conducts an  excavation in a new location is refers scientific explanation because explanation is needed for it.

The rocks present in western Africa  and eastern South America formed  at the same place and at the  same time is scientific observation because the scientists takes the data.

Even if modern organisms are  found in ancient portions of the  fossil record, this wouldn't challenge the theory of evolution in any way is refers to scientific explanation.

The cloning of organisms is an  exciting area of study, and more  resources should be be devoted  to it so it is refers as scientific explanation.

The age, type, and composition of  ancient rocks in western Africa are  nearly identical to the age, type,  and composition of rocks in  eastern South America is scientific observation which is taken by the scientist through research.
