Finally stones, pebble(卵石)a
45、nd grains of sand were formed. Many sorts of plants and animals lived and died on the surface of the earth. Their remains mixed up with the stones, pebbles and formed soil. The outmost layer of the earth is soil.There are many ways in which large pieces of rock break into smaller ones. Wind, water,
46、heat and cold help to break up rocks. When winds blow grains of sand against a large rock for a long time, the softer layers of the rock are slowly worn away. These leave holes and crack(裂縫)in the rock, which become bigger and finally the rock breaks up into smaller pieces.The moving water of stream
47、s and rivers also help to break up rocks. As the water moves along, it carries with it small pieces of rock. These rub the larger ones. Thus, the larger rocks are worn down to smaller pieces.The heat of the sun is also helpful to breaking up rocks. When the sun shines, the rocks become very hot. If
48、these rocks are suddenly cooled, they may crack. Ice also plays a part in making soil. Water in the cracks can turn into ice in cold weather. As this happens, it becomes bigger and the cracks become wider, and finally break into smaller pieces.71. According to the passage, soil . A. forms very slowl

If a large rock never moves, it will never break up. C. Even if a large rock never moves, it will break up. D. Ice
51、 in the cracks helps to break up rocks75. The best title for this passage should be . A. Soil from Rocks B. Ways to Break up Rocks C. Soil on the Earth D. Soil, Outmost Layer of the EarthEDo you know that you can use your watch as compass(指南針)on a sunny day? Look at the watch which is on your hand a
52、nd point the hour hand in the direction of the sun. Imagine a line which runs from the center of the watch through a point halfway between the hour hand and number one. This line will point south.In the northern half of the earth the sun is in the south at noon. In our country the real noon is one oclock.
