Did you know that the average depth of the ocean is about 2.3 miles? That’s really deep! The ocean is so big that there are still many parts we don’t know much about, even with all the cool technology we have today. Let’s learn some amazing facts about the ocean. Ready? Let’s hop into our imaginary boat and explore!
The ocean is enormous! It’s made of salt water and holds almost all of Earth’s water—about 98%! That’s a lot of salty water!
If you’ve ever been to the ocean, you might have heard waves crashing on the shore. Waves can form in a few different ways. The most common way is when the wind blows across the ocean’s surface. This creates surface waves. The wind is strong and full of energy, which makes the water ripple. The stronger the wind, the bigger the waves!
Waves can also be caused by gravity. The Sun and the Moon pull on the Earth, creating tides. When the Moon is closer to the Earth, it pulls the water up, causing high tide. When the Moon is farther away, the water level goes down, causing low tide.
Here’s a fun fact: Every day, there are two high tides and two low tides, but they don’t always happen at the same time. Isn’t that cool?
Sometimes, waves are caused by underwater explosions. Volcanoes and earthquakes can happen under the ocean, making the water move and create huge waves called tsunamis.
The ocean is more than two miles deep on average, but it can be shallower or deeper in different places. Just like land, the ocean floor has different levels. The shallowest part is the continental shelf, which is near the land. That’s where you play when you visit the beach.
After the continental shelf, the ocean floor slopes down into basins, and at the bottom are flat areas called Abyssal Plains. There are even underwater mountains and volcanoes! Even with all our technology, about 90% of the ocean is still unexplored.
Here’s an interesting fact: The Mariana Trench is a deep crack in the ocean floor. It’s 36,198 feet deep, which is about 7,000 feet taller than Mount Everest if it were a mountain!
The ocean is full of life. Scientists think there are between 700,000 and 1 million different species in the ocean, and many of them haven’t been discovered yet. This doesn’t even include the millions of tiny microorganisms living there.
True or False: The ocean makes up only 10 percent of Earth’s total water.
Answer: False. The ocean contains almost all of Earth’s water—around 98 percent.
Fill in the blank: Waves that are caused by wind are called __________.
Answer: Surface waves.
True or False: Scientists estimate that there might be as many as one million species living in the ocean.
Answer: True.
The ocean is a fascinating part of our planet, full of mysteries. Maybe one day you’ll become a scientist who explores the ocean and makes exciting new discoveries!
Hope you had fun learning with us!
Wave Experiment: Create your own waves at home! Fill a shallow tray or a large bowl with water. Use a straw to gently blow across the surface of the water and watch how waves form. Try blowing harder or softer and observe how the size of the waves changes. Discuss with a friend or family member how this experiment relates to the way wind creates waves in the ocean.
Tide Tracker: With the help of an adult, find a safe spot near a beach or a body of water where you can observe tides. Visit the spot at different times of the day to see the changes in water level. Draw pictures or take notes about what you see. Can you predict when the next high or low tide will be? Discuss how the Moon’s position might be affecting the tides you observe.
Ocean Floor Model: Use clay or playdough to create a model of the ocean floor. Include features like the continental shelf, abyssal plains, and underwater mountains or volcanoes. Once your model is complete, explain to a friend or family member what each part represents and why the ocean floor is so diverse. Imagine what kinds of creatures might live in each part of your model.

**Ocean Facts for Kids**
Did you know that the average depth of the ocean is 2.3 miles? The ocean is so vast that large parts of it still remain a mystery, even with all the technology we have today. We are going to talk more about the ocean and learn some cool facts along the way. Ready? Let’s jump into our imaginary boat and cruise!
Now that we are cruising on the ocean, let’s observe some of its characteristics. First off, oceans are huge! The ocean is made of salt water and contains almost all of the water on Earth—around 98%, to be more precise. Wow, that is a lot of salt water!
If you have ever seen the ocean in real life, you have probably heard waves crashing against the shoreline. These waves can be formed in different ways. First, waves can form when the wind blows across the surface of the ocean. These surface waves are the most common type of wave because the wind is powerful and has a lot of energy. It creates friction between the wind and water molecules, which makes the water ripple. The stronger the wind, the bigger the ripples!
Waves can also be formed by gravity—the gravitational pull of the Sun and the Moon on the Earth, to be exact. These waves are called tides, and they are affected by the Moon’s location in relation to the Earth. When the Moon is closer to the Earth, it pulls on the tides, causing the water to rise. This is called high tide. When the Moon is farther away, it does not pull as hard on the water, which causes the water level to lower. This is called low tide.
Here is an interesting fact about tides: every day, the Earth has two high tides and two low tides, though they do not always occur at the same time. Cool, right?
Another way that waves can form is through underwater explosions. Volcanoes and earthquakes can happen under the ocean, which causes the water to move and create waves. Some of these waves are gigantic and are called tsunamis.
Remember how we mentioned that the average depth of the ocean is over two miles deep? Well, in some places, it is much shallower, and in others, it is much deeper. Like dry land, the ocean floor has many different levels. The shallowest part of the ocean is called the continental shelf, which is right next to land. That is the part of the ocean you see and play in when you visit the beach.
After that, the ocean floor slopes downward into basins, and at the bottom of the basins are vast flat plains called Abyssal Plains. There are even mountain ranges and volcanoes! Even with all of our technology, around 90% of the ocean is still unmapped by sonar.
Here is an interesting fact: the Mariana Trench is a deep underwater crack in the ocean floor. It is 36,198 feet deep, which, if it were a mountain, would be around 7,000 feet taller than Mount Everest.
The ocean is also teeming with life. Marine biologists estimate that there are between 700,000 and 1 million different species in the ocean, with over two-thirds of those species yet to be discovered. That estimate does not include the millions of microorganisms living in the ocean.
Now that we have learned some cool and interesting facts about the ocean, let’s dock our boats and review!
**True or False:** The ocean makes up only 10 percent of the Earth’s total water.
**Answer:** False. The ocean contains almost all of the water found on Earth—around 98 percent.
**Fill in the blank:** Waves that are caused by wind are called __________.
**Answer:** Surface waves.
**True or False:** Scientists estimate that there might be as many as one million species living in the ocean.
**Answer:** True.
The ocean is a fascinating part of the Earth that is still mysterious in many ways. Maybe one day you can become a scientist who explores and studies the ocean and make an exciting new discovery!
