Forces of Nature written by Jack Gabo linscy
rainbow The forces of nature are always at work all around us. They are very strong and they never stop. We can see and feel their power in the world. Think about the wind on your face, plants growing, rain falling, the seasons changing, dry deserts and icy lands, volcanoes erupting, earthquakes shaking, and rivers flowing. These things all happen because of the forces of nature.
Earth The Sun is a strong force of nature. It makes night and day on Earth. As Earth spins around and around, the side facing the Sun is in daylight. The side that faces away from the Sun is in Earth's shadow. It is night time there until it turns around into the sunlight again. One part of Earth has daytime while the other part is in darkness.
Sunlight is the force of nature that warms Earth and makes plants grow. If there was no Sun, there would be no plants on the land or in the sea. There would be no animals, insects, birds, fish, or people because there would be no plants for them to eat. If there was no Sun, the world would be a cold, dark place with no living things.
tornado Sunlight is also the force of energy that makes the winds blow. The Sun warms the air and makes it move. The wind is moving air. A breeze is a light wind. We can fly kites and sail boats in a breeze. But sometimes the wind becomes stronger and blows much harder. Strong winds can make sandstorms and snowstorms, hurricanes, and tornadoes. Hurricanes sink boats, blow down houses, and knock over trees.
eruption Sometimes the forces of nature work from under the ground. A volcanic eruption starts from deep inside Earth, where there is red-hot melted rock called magma. The magma pushes up through cracks in the rock under a volcano. Then suddenly it erupts, with gas, lava, ash, and steam flying into the air. Rivers of red-hot lava run down the sides of the volcano.
