The correct answer is - Exports grew significantly in the 1820's.
This graph shows us the exports of opium by the British toward China. Starting from the year of 1729 the exports of opium in China constantly grew, though relatively slowly. In 1790 there's significant rise in the exports, but that it kind of stagnates and the growth is minimal in next three decades.
<em>From the begging of the 1820's to the end of the 1820's the exports of opium start to grow very quickly. The rise in exports was so quick that in just this decade the exports of opium went up by around three times (tripled).</em>
That trend of rapid growth in the opium exports continued in the next decade, the 1830's, as well.
A timeline is the presentation of a chronological sequence of events along a drawn line that enables a viewer to understand temporal relationships quickly. The term is also sometimes extended to mean a chronology that is tabular, year-by-year paragraphs or purely conceptual. Increasingly, timelines are illustrated in infographics combining text and graphic images for a better presentation.
The effect of greenhouse gases on the Tundra ecosystem will cause Increased greenhouse gases will increase the overall average temperature of the region, resulting in the melting of the polar ice.
The tundra is a scientific term to refer to the polar geographic region characterized by:
- Low growing vegetation.
- Frozen subfloor.
- Absence of arboreal vegetation.
- Soils that are covered in moss, lichens, snow, or ice.
- In some places they are swampy.
This region is being affected by greenhouse gases because they heat the poles, cause a thaw, and the water level is rising making the tundra an exclusively marshy region.
