Why do boats float in water answer?
The air that is inside a ship is much less dense than water. That’s what keeps it floating! As a ship is set in water, it pushes down and displaces an amount of water equal to its weight.
What causes a boat to sink?
Many boats sink because of leaks at thru-hulls, outdrive boots, or the raw water cooling system, all of which are routinely implicated when boats sink at the dock. Many boats sink after coming down hard off of waves and splitting open. Once a boat starts to sink, it will gain momentum as it settles into the water.
Why do things sink and float?
It depends on the density of the object. An object is made of substances that are themselves made up of molecules. Density is a measure of both how massive those molecules are, and how closely packed together they are. If the object’s total density is greater than that of water, it sinks, but if it is less, it floats.
How do you explain floating and sinking to a child?
Before explaining why items sink or float, ask your children why they think an object sinks or floats. They may guess it’s because of size or weight or construction. Then, explain that items sink or float based on their density. Density is determined by how close or far apart molecules are within an item.
Does size affect floating and sinking?
Students will observe that as long as the shape and material are the same, size does not affect whether an object will sink or float.
Which is the only planet that rotates clockwise?
Venus
Can you live on Saturn?
While planet Saturn is an unlikely place for living things to take hold, the same is not true of some of its many moons. Satellites like Enceladus and Titan, home to internal oceans, could possibly support life.
What is the hottest planet?
What are the 15 planets?
Planets in Our Solar System
- Mercury. Mercury—the smallest planet in our solar system and closest to the Sun—is only slightly larger than Earth’s Moon.
- Venus. Venus spins slowly in the opposite direction from most planets.
- Earth.
- Mars.
- Jupiter.
- Saturn.
- Uranus.
- Neptune.
Is Venus hot or cold?
The average temperature on Venus is 864 degrees Fahrenheit (462 degrees Celsius). Temperature changes slightly traveling through the atmosphere, growing cooler farther away from the surface. Lead would melt on the surface of the planet, where the temperature is around 872 F (467 C).
Why is Venus called Earth’s sister?
Venus is a terrestrial planet and is sometimes called Earth’s “sister planet” because of their similar size, mass, proximity to the Sun, and bulk composition. It is radically different from Earth in other respects.
Is Venus Earth’s sister?
Venus is very similar to Earth in size and mass – and so is sometimes referred to as Earth’s sister planet – but Venus has a quite different climate. Venus’ thick clouds and closeness to the Sun (only Mercury is closer) make it the hottest planet – much hotter than the Earth.
Is Venus visible every night?
Venus is always the third-brightest object in the sky behind the sun and the moon, and it’s always brighter than the brightest stars. However, because it orbits relatively close to the sun, it’s only ever visible for a short time after sunset or before sunrise.
What is the most beautiful planet in the galaxy?
planet Saturn
What is the prettiest moon?

- The Moon We Know Best.
What is the most dangerous planet?
What is the most beautiful star?
Sirius, also known as the Dog Star or Sirius A, is the brightest star in Earth’s night sky. The name means “glowing” in Greek — a fitting description, as only a few planets, the full moon and the International Space Station outshine this star.
What color is the hottest star?
Blue stars
Why do stars twinkle?
As light from a star races through our atmosphere, it bounces and bumps through the different layers, bending the light before you see it. Since the hot and cold layers of air keep moving, the bending of the light changes too, which causes the star’s appearance to wobble or twinkle.
What is the brightest thing in the universe?
The Brightest Quasar of the Early Universe Shines with the Light of 600 Trillion Suns. Scientists have discovered the energetic core of a distant galaxy that shatters the record for the brightest object in the early universe, blazing with the light equivalent to 600 trillion suns.
What star is brighter than the sun but not hotter?
Betelgeuse
What is the fastest thing in the universe?
Laser beams travel at the speed of light, more than 670 million miles per hour, making them the fastest thing in the universe.

What two planets have no moons?
The answer is no moons at all. That’s right, Venus (and the planet Mercury) are the only two planets that don’t have a single natural moon orbiting them. Figuring out why is one question keeping astronomers busy as they study the Solar System.
