How we can classify land on the earth?
Land on the Earth The earth is a huge ball, but it is not smooth all over like a ball that you bounce or roll. The earth’s surface is full of bumps and dips, but some parts of it are smooth. Where there’s no water, there is land. Some of the earth’s surface is on…

How can you find the parts of the world’s ocean?
The World’s Ocean Do you think the earth’s surface has more land or more water? Would you believe that most of the planet is covered with water? It’s true. The land we live on, even the giant continents, are really just like big islands in a huge ocean. Different parts of the ocean have different…

What makes waves?
On a quiet day, you can hear the waves roll in and splash near the shore. On a stormy day, they thunder. Waves are made by wind blowing along the top of the water. The water seems to be moving forwards – but it only moves up and down. A cork floating on the water…

What are glaciers?
All that ice A glacier is a large mass of ice that flows slowly over land in cold Polar Regions and high mountain valleys. Glaciers begin as snow on a mountaintop. As more snow falls, the weight of the new snow squeezes the snow already there. The snow on the bottom of the pile turns…

Which are the various parts of the sea?
The Bottom of the Sea The sea floor has many mountains, plains, deep valleys, and even volcanoes! Its mountain ranges are longer and wider than those on land. Its valleys are longer and deeper, too. The earth’s surface is covered with a rocky crust. The high parts are the continents and islands, and the low…

What are Deserts?
The glowing sun glares down on a vast sea of sand. As far as the eye can see, sand stretches in great brown ripples. The air is so hot it seems to shimmer as it rises from the sand. Not even the tiniest green plant is in sight. Most people picture this endless, hot sandy…

What are Plains?
Have you ever travelled across land where the sky seems bigger than the countryside around you? If so you probably saw a part of the earth called a plain. The land is so flat that you can see great distances all around. Most plains are lower than the land around them, but they are not…

What are Valleys?
If the highest part of the land is a mountaintop, what do you think the lowest place is? That’s right – a valley. Most valleys begin as land with a stream or river running through it. As the river flows along, it breaks off pieces of the land and carries them away. This deepens the…

What are the consequences of ground shakes?
The Ground Shakes The ground shivers, shakes, and rumbles. Whole sections of land move, and even mountains seem to move. What is happening? It’s an earthquake! What causes earthquakes? Earthquakes start in the earth’s crust. Pressure builds and pushes rocks until they bend. If you bend a stick long enough, it snaps and breaks. The…

How Islands were invented?
An Island is born Day after day, huge explosions filled the air. The ocean sizzled as hot rock and ash shot up from the sea floor. Soon, a large mound of dark, melted rock rose out of the water. Far out in the sea, a new volcano was born. After it rose above the surface…
