Practice for weather, life and soil

Here is a plan for any question. First read it slowly and underline the key words. Then think of the answer before you look at the choices. Cross out choices you know are wrong, and say why. Now the facts you need. Weather is the air at one place and time; climate is the usual weather over many years. A thermometer measures temperature and an anemometer measures wind speed. Plants lose water vapour from their leaves, and evaporation takes in heat while condensation gives out heat. Rain, snow and hail are precipitation. Unequal heating makes air rise and sink, and that moving air is wind. Air pressure is lower on a mountain top, where the air is thinner. Sand heats up and cools down faster than water, and the oceans help the climate by storing heat, moving it around and taking in carbon dioxide.
