This is an article from Curious Kids, a series for children. The Conversation is asking kids to send in questions they'd like an expert to answer. All questions are welcome - serious, weird or wacky!

What makes the Earth spin on its axis every day? - Reid, age 5, Melbourne.

To answer this tricky question, we have to look back in time to when the Earth was born, 4.5 billion years ago. We have to ask: why did the Earth start spinning in the first place?

When our solar system formed out of a gas cloud, called a nebula, there was lots of dust and gas coming together due to the force of gravity. The dust and gas was already moving around in a circle. As it all clumped together to form the Sun and planets, these new objects started to spin - and then spin faster.

Read more: Curious Kids: Why do our ears pop?

How the spin sped up

When you make a spinning object more compact, it spins faster. It's just like how an ice skater or a ballerina brings in his or her arms when they want to spin faster.

So when all of the rocks in the clump of dust and gas started coming together, that made the Earth's spin speed up.

We've covered what made the Earth start spinning, and what made it pick up speed. But why does it keep spinning?

Why the spin continues

In theory, a spinning object will just keep spinning forever unless you add energy or take it away.

Imagine a spinning top. You added energy to it by starting the spin off with your hand. Eventually it stops because the ground it is spinning on is taking energy away from the toy top through something called friction.

Friction is where something rubs on or drags on an object and takes energy away. Have you ever slowed yourself down while you're riding downhill by dragging your foot on the ground? That's friction.

There's not much friction in a fidget spinner toy. That's why they can spin for so long.

But eventually, even the air around you can cause friction and slow down a spinning top or a fidget spinner.

Back to Earth

Now imagine the Earth floating in space. It will keep spinning unless something slows it down. It would take a LOT of energy to slow down the spinning Earth because it is so big.

It's not spinning on the ground, so the ground won't slow it down. There's no air outside our own atmosphere to slow it down either. That is why the Earth has continued to spin for a very long time.

Read more: Curious Kids: will the universe expand forever, or contract in a big crunch?

However, some things are slowing the Earth down or could change its spinning in the future.

You might have heard that the Moon causes the waves and tides in our oceans. Because of this, the Earth is slowing down very slowly (about 1 second every 50,000 years). As a result, the Moon is also slowly moving away from us.

When the Earth and Moon were very new, the Moon was much closer (in fact it is thought that the Moon was once part of Earth but they came apart during an explosive collision with a huge asteroid.)

How do we know that? Well, scientists examining rocks realised that there used to be many more days in a year. In the age of the dinosaurs, a day was 22 hours rather than 24 hours that it is today.

The Sun's gravitation also causes the Earth to slow down a bit too. And if an asteroid or comet hit the Earth, that might speed us up, slow us down or even knock us over (scientists think this may be what happened to Uranus, which is actually on its side - you can tell by the vertical stripes the clouds make rather than the horizontal ones you see on Earth, Jupiter and Saturn).

Here are some more cool planet spinning facts:

All the planets have different day lengths. Mercury's day is about 59 Earth days, while Jupiter's day is only 10 Earth hours long.

Venus has the longest day (if you define day as meaning one full spin) of nearly 117 Earth days. It actually spins in the opposite direction to all of the other planets except Uranus.

These different day lengths are because of how the planets were formed and what knocked into them when they were very young.

If there's one thing most students look forward to, it's learning to tell time. Once you know how a clock works, you keep your eye on it all the time! ( totally intended!)

Whether you're keeping track of how many minutes left until lunch...or until soccer practice starts...or until your favorite show comes on...or until bedtime, you probably find yourself keeping track of the time all day long.

If you think about it, so much of your life involves - and sometimes revolves around - time. Give it some thought. You have to get up at a time in the morning. Why? Because you have to be school at a time. You get out of school at a time. Television shows come on at particular times. You have to go to bed at the same time each school night.

Time is a big part of our lives. But did you ever give any thought to how it came to be? Who invented time? Was it even invented at all? These are the things we're WONDERing about today!

Time wasn't really invented. After all, it's always been around since...well...the beginning of time! Some people think of it as a that helps to order our lives.

Time can be thought of in many ways. One of the simplest is to think of time in terms of the , the , and the . These three ever-changing bodies of experiences differ and change based upon the passage of time.

For example, you're reading this paragraph right now in the . That last paragraph? You read that in the . The next paragraph? You're going to read that in the . What separates these events? Probably no more than a few seconds.

The , , and can be separated by hours, days, weeks, months, and years. These are all units of measure that were created to help us keep track of the passage of time.

There are no measures of time. Time just rolls on and on, never stopping. To help us better understand and navigate our lives, however, people long ago assigned standards of measurement that would help to get a grasp of the passage of time.

The natural of the Earth on its and the revolution of the Earth around the Sun give us our two most basic measurements of time. The time it takes the Earth to rotate once on its (about 24 hours) is called a day. The amount of time it takes the Earth to once around the Sun (about 365 days) is called a year.

These units have been further divided into even smaller units of measurement . Years are broken down into months and weeks; days are measured in hours, minutes, and seconds. And our environment impacts even these categories. The month, for example, developed from the cycles of the moon. These various units help us communicate about and keep track of time - , , and .

Take some...time...today to think deeply about time. What do you think it's like? Is it just a way for us to better understand our lives? Or does it really exist in some way, such that it flows and could be traveled either backwards or forwards if the means existed to do so. What do you think? What does time mean to you?

Our Science

The answer is 'yes' with some big 'ifs'. Here are 3 things we must do right now.

The science is in: We don't have to accept doom and gloom for the Earth. Together, we can slow the dual crises of climate and biodiversity loss. This is a hopeful wake-up call, but only if we act with great urgency.

A future in which people and nature thrive together. What we do between now and 2030 will determine whether we slow warming to 1.5 degrees Celsius-the level scientists agree will avoid the worst impacts of climate change-while also conserving enough land and water to slow accelerated species loss. This vision of the future is achievable, and we must join together and put all our effort to make this vision a reality.

The 3 Things We Must Do

The stakes couldn't be higher. If we follow the path that science shows us, we have the power to save nearly all habitat types across the world's lands. That's a huge win for wildlife, birds, plants, insects and the diversity of life that makes our natural world such a treasure.

We truly do have the power to build a future in which nature and people can thrive together.

A more sustainable path is possible. But we need to rally individuals, governments, companies and communities around the world to take action with us over the next decade. When we're at the table with leaders around the world, it gives us great strength to show how many people are with us.
