Health care findings are overtaking immigration and the economy. spending on the NHS has been increasing at around four per cent each year in real terms; but over the ten years from 2010 to 2020 it will only increase at around one per cent. This leaves a big shortfall in funding. while older people are big users of the NHS, the average future 75-year-old is likely to be healthier than the current 75-year-old and, hence, need less health care. And while demographic changes have driven historic increases in spending, they tend to account for a relatively small share of the growth in NHS spending.
Answer:
The answer is Option B: plate tectonics.
Explanation:
Plate tectonics is a theory about the structure of the earth's crust. In plate tectonics, the continents are viewed as a part of a system of rigid lithospheric plates which move slowly over the underlying mantle of the Earth. The model for plate tectonics builds on the concept of continental drift, which is an idea developed during the first decades of the 20th century. In continental drift theory, all the world's continents were once joined into a land mass that geologists have called Pangea during the late Paleozoic and early Mesozoic eras. It began to break up about 175 million years ago. In the beginning in the late Triassic, the continents began to break up with Laurasia comprising with what is North America and Eurasia and Gondwanaland which was South America and Africa, India, Arabia, Antarctica, and Australia. The shift in plates and their movement create mountain ranges and continents form and move to different latitudes that change the climate as these land masses moved.
