  Water Cycle Step #1: Water evaporates from the Earth’s surface . If you spill a glass of water outside you will notice that a few hours later the water is gone! That is because water slowly turns from a liquid into a gas called water vapour. The process of water turning from a liquid into a gas is called evaporation. Evaporation happens faster on a hot day. That is because the evaporation of water outside takes energy from the sun! The hotter it is outside, the faster water will evaporate. Since water in its gas form has no colour, we cannot see it. It just goes into the air. Water Cycle Step #2: Water condenses to form clouds Water vapour rises up in the sky due to the sun’s heat. Once the water vapour rises high enough it condenses into water droplets. Condensation is the process of water turning from a gas into a liquid . You have probably experienced condensation if you have had a cold glass of water at a restaurant. As the cold glass sits on the table, water vapour from the...

Worksheet   A guide to climate change

 1. Why is the temperature not the same in all places on Earth? Because the Sun is so big compared to the Earth, only the rays that come straight at the Earth will hit it. Areas of the Earth that are hit by direct rays are warmer than areas that are hit by indirect rays. 2.What factors does the air temperature of a place on Earth depend on? A) On the distance of the place from the Equator: the air gets colder as we move away from it and approach the poles (with increasing latitude). B) On the altitude of the place: the air gets colder as we get to a higher altitude. C) On the distance of the place from the sea: The land heats up and cools faster than the sea-so the air above the land is warmer in summer and colder in winter. On the contrary, in the same place, above the sea it is cooler in summer and warmer in winter. 3.What do we call winds and where do they owe their creation? Winds are the lateral and vertical movements of the wind. They are due to: the temperature differences b...

What is a map? A map presents information about the world in a visual way. It shows the shapes of countries, the distances from one place to the other, locations of lakes, seas, mountains, streets, rivers and many more. Kinds of maps There are different kinds of maps:  Physical: they show the physical features of an area eg. mountains, rivers, lakes,etc Political : they show the states, national boundaries , capital and major cities etc Thematic : they give details of different aspects like weather, time, industries etc Elements of a map: The title gives basic information about the map. A legend or key explains all symbols used in a map. legend A map's scale shows the relationship between distances on the map and the real distances. scale A map always shows the cardinal directions with the aid of a compass rose. The upper part of a map shows the north, the bottom part of a map shows the south, the left part of a map shows the west and the right part of a map shows the east. comp...
