1. These deadly mushrooms include such names as death cup, and destroying angel.

2. Landscapes that occur where deep beds of clay, and soft, weak rocks are found in arid regions, and the rainfall is not enough to support vegetation, so when heavy rain comes, it washes gullies in the soft ground, creating bizarre formations.

3. When there are exceptionally high tides, the water is forced into narrow or shallow channels, sometimes advancing upstream in a solid wall, known as tidal ……

4. A microscopic single-celled alga, one of the most abundant plants in oceans around the world.

5. Unlike a crag-and-tail, this is formed from glacial debris, streamlined by the moving ice sheet, without requiring a massive rock obstruction at the front.

6. Narrow winding ridges of debris, thought to be formed by streams that flowed in subglacial tunnels, dropping sediments in their beds as the glaciers retreated.

7. Long, deep, narrow, valleys excavated by glaciers, that open to the sea.

8. Irregular hills formed where glacial melt-water poured into crevasses, or along the edge of and ice sheet, dumping mounds of debris that remained as hills.

9. As the ice sheets retreated, chunks of ice broke off, were buried in the sand and gravel, and when the ice melted the covering debris caved in, forming these rounded basins.

10. Such earth movements usually occur on slopes that are so steep that the friction between soil particles or rock layers is barely enough to withstand the downward pull of gravity, and can be triggered by earthquakes, or by heavy rain.

11. Explosions of ash and cinder scooped out these flat-bottom depressions, many of which fill with water to form lakes.

12. Generally caused by strong tidal currents, surging through constricted channels. These whirlpools can be dangerous to small boats.

13. The heavy rains that this periodical wind brings changes direction between land and sea, according to the season, but when it reverses direction, it can give rise to tornadoes and hurricanes.

14. They are formed by movement of the Earth’s crust from faults, where huge blocks slip along the fractures, stress causing the crust to rumple, or causing volcanoes.

15. Fungi such as these, are simple non-flowering plants that lack true leaves, stems, and roots, and lack chlorophyll, therefore are unable to make their own food.

16. These moulds in their active phase are jelly-like blobs, that ingest micro-organisms and bits of decaying plants, then they make their way to higher, drier places, form fruiting bodies, and start the cycle anew.

17. Strobili, specialized reproductive structures, are made up of small overlapping scales, each concealing a tiny one of these cases.

18. This was formed when the surface of the lava flow began to cool and harden, but beneath the solid crust the molten lava drained away leaving a tunnel-like opening.
