๐ Volcanoes erupt because there is hot, melted rock called magma deep inside the Earth. When the magma gets too hot and bubbly, it pushes up through cracks in the ground and comes out as lava! ๐๐ฅ
Imagine shaking a soda bottle and then opening itโthe bubbles rush out! That's kind of like how a volcano erupts!
๐ช๏ธ A tornado is like a big, spinning wind tunnel! Inside, there's lots of strong wind that goes round and round very fast. It can pick up things like leaves, dirt, and even toys if they're outside! ๐ฌ๏ธ
But don't worryโtornadoes are far away and grown-ups keep us safe when they happen. Tornadoes are like nature's vacuum cleaners, but they're very loud and scary!
Radiation is like tiny invisible waves or little energy particles that come from some things around us. ๐ Some radiation is good, like the warm sunlight that helps plants grow! But some can be not so good, like when we use sunscreen to protect our skin.
Radiation can come from the sun, rocks, and even some machines in hospitals. Doctors use special kinds of radiation to take pictures of our bones! ๐ฅ
Electricity is like magic power that makes lights shine and toys work! โก It comes from big machines called power plants. Some power plants burn coal or gas to make heat, and that heat turns water into steam. The steam spins a big wheel called a turbine, and that makes electricity!
Other power plants use wind or sunlight to make electricity. Wind spins big fans (wind turbines), and sunlight is caught by special panels (solar panels).
A nuclear power plant is like a big, super-hot teapot! ๐ It uses tiny things called atoms to make heat. This heat turns water into steam, which spins a big wheel called a turbine. The turbine makes electricity that powers our homes and toys! โก
It's safe because scientists and engineers make sure everything is controlled and protected. ๐
There are so many stars in the sky that we can't count them all! ๐ They twinkle like tiny lights at night.
If you look up, you might see hundreds, but there are actually billions and billions of stars in space! โจ
Long, long ago, people thought the Earth was flat like a pancake ๐ฅ. But smart people noticed that when ships sailed far away, they slowly disappeared from the bottom up! If the Earth was flat, the ships would just get smaller and smaller, but they don't! ๐
Also, when there's an eclipse (when the Moon covers the Sun), the shadow on the Moon is round. That's another clue that the Earth is round like a ball! ๐
๐ The Earth looks flat because it's so big! Imagine standing on a huge ballโit would feel flat under your feet. That's what happens with Earth! ๐
When you look around, you can't see the curve because the Earth is much bigger than you. It's like being a tiny ant on a big beach ballโyou can't see the whole ball at once!
When we throw trash away, it goes to a special place called a landfill ๏ฟฝ. Big trucks take it there, and people bury it under the ground. Some trash can be recycled โป๏ธ, which means it gets turned into new things!
Remember to throw trash in the bin so the Earth stays clean and happy! ๐
The sea is blue because it reflects the color of the sky! ๐ When the sun shines, the sky looks blue, and the water copies it like a big mirror. Sometimes, the sea can also look green or gray, depending on the weather and what's inside the water.
๐ก Fun fact: Did you know that if you take a cup of sea water, it will look clear, not blue? The blue color only shows when there's a lot of water together!
