<span>Although China's agricultural output is the largest in the world, only about 15% of its total land area can be cultivated. China's arable land, which represents 10% of the total arable land in the world, supports over 20% of the world's population. </span>
The negative effects of geological structures in our environment can be landslides occurring on unfavorably oriented geological structures causing damage and sometimes loss of life on highways and railways, for example.A positive effect of geological structures is that where there are subduction zones, mineral deposits can form above them on the adjoining continents like in British Columbia on the west coast of North America. Also, faults and fractures can allow hydrothermal fluids charged with metals to form ore deposits.
Abundant most likely means: more than sufficient without being excessive. plentiful implies a great or rich supply.
It's the picture of the Atlantic ocean. On average, the Atlantic Ocean is growing at a rate of about 2.5 cm/year.
So,
1. Since 2000, it grows about (2018-2000) x 2.5 = 45cm
2.( 2018 - 1492) x 2.5 = 1315 cm
3. 200 x 2.5 = 500 cm
4. The <span> Atlantic begin forming since mesozoic era</span>
<span>When applied to earth’s atmosphere, the greenhouse effect is related to the "Amount of Carbon dioxide in the Atmosphere"
Hope this helps!</span>
