It began around 2.6 million years ago and ended about 12,000 years ago when the Holocene began. (11) 2. The output of water from a glacier as the ice melts. You get more of this than accumulation in the lower part of the glacier so its called the zone of ... (8) 5. Bits of rock stuck in the ice grind against the rock below the glacier, wearing it away, like sandpaper. (8) 7. The removal of weathered material via agents such as water, wind, or in this case ice. (7) 8. Warmer periods between glacial periods when ice retreats. Each one lasts for around 10,000 years. We are currently in an interglacial period that begun 10,000 years ago, and today ice covers 10% of the Earth's land surface. (12) Down 2. A steep-sided ridge formed when two glaciers flow in parallel valleys. The glaciers erode the sides of the valleys, which sharpens the ridge between them. E.g. Striding Edge, Lake District. (5) 3. The epoch we are in now. (8) 4. The breaking down of rocks, soils and minerals through direct contact with the atmosphere. (10) 9. Begins as a hollow containing a small glacier. As the ice moves by rotational slip, it erodes the hollow into a steep-sided, armchair shape with a lip and steep back wall. When the ice melts a tarn is sometimes left. E.g. Red Tarn. (6) 10. Masses of ice that fill valleys and hollows, that move downhill under the force of gravity. Often extend from an ice cap or ice sheet like long tongues of ice. (7)
