Across 1. A active volcano in Antarctica 3. Small, leafy-stemmed plants that grow in carpet-like mats and tufts on moist ground. Particularly abundant in maritime regions of Antarctica where conditions are too harsh for other types of plant. In Antarctica mosses often accumulate in large "moss banks". 4. An area where there is little moisture due to there being little precipitation is low and evaporation is high. Precipitation usually is less than 25 centimetres a year (10 inches). Large deserts include the Sahara Desert in Northern Africa or the continent of Antarctica. 7. when snow falls on glacier 8. Ronald was a Norwegian explorer of the polar regions when he discovered the south pole in 1911 10. A theory that ties together many observations made about the activity and movement of Earth's crust (earthquakes, volcanoes) and creation of ocean basins. Plate tectonics divides the surface of the globe into a number of rigid plates that move around the earth's surface over the period of millions of years. 14. A theory that ties together many observations made about the activity and movement of Earth's crust (earthquakes, volcanoes) and creation of ocean basins. Plate tectonics divides the surface of the globe into a number of rigid plates that move around the earth's surface over the period of millions of years. 16. Rain, snow, hail, sleet etc. moisture falling from clouds to the surface of the Earth, usually as rain, snow, and ice. The amount of precipitation is always measured as water or rain equivalent so allowing for the fact that snow can have various structures and densities 18. Imaginary lines that allow for the measurement of position north or south of the equator. Latitude is measured in degrees (one degree - 60 nautical miles, or 111 kilometres). The equator is at a latitude of 0° and the poles lie at latitudes of 90° north (North Pole) or 90° south (South Pole). Lines of latitude differ in length according to how far north and south they are. 19. Animals. Antarctic fauna includes seals, penguins, whales, krill, ice-fish, nematode worms, mites, and wingless midges (plus a few other animals). Also sometimes used in the phrase "charismatic mega-fauna" large animals with charisma - penguins, seals, whales 20. Frozen or partially frozen rain that form when rain passes through a layer of air that is below the freezing temperature, falls to earth as a slush. Freshwater.

Down 1. Douglas is a famous Antarctic explorer who reach the Mount Erebus also his team reach to the south pole 2. the point on Earth's surface that a south-seeking compass needle seeks. At the South magnetic pole a compass needle will point vertically downwards. This point is currently off the coast of Wilkes Land and wanders around. 5. Fragments of rock that reach the Earth from beyond the atmosphere. Most are believed to come from asteroids, some are believed to be pieces from other planets. Antarctica is a particularly good place to find meteorites as they show up against the snow and ice and are accumulated in some places by the flow patterns of ice streams and glaciers. 6. The study of Earth, the history of the rocks, what processes that have occurred and are occurring on and within it (to the rocks). 9. water vapour that falls under gravity 11. A large piece of floating ice that has calved, or broken off, a glacier or ice shelf. Icebergs occur in lakes and the ocean and can be vast, the size of islands or small countries. Freshwater. 12. the coolest continent 13. when a body tissue dies off example from a toe 15. Moving from one area to another. Some animals migrate in certain seasons to find better conditions, such as weather, food, or for breeding. Many whales migrate to the Southern Ocean in the summer to feed on the large the quantities of krill for example. 17. Very dry. An area with little rain or precipitation of any kind (snow, hail, sleet etc.) usually less than 25 centimetres (10 inches) of annual rainfall, Antarctica is largely classed as arid.
