The Churchill River is a really big river located in Canada, which is a country far away from us. The river starts in a place called Churchill Lake and goes all the way to the Atlantic Ocean.
Now, let's imagine that the river is like a long road that water takes to reach the ocean. Water from different places like rain, snow, and small streams join together and start traveling along this road. The road or the river is a bit like a snake because it twists and turns a lot.
As the water travels down the river, it carries a lot of things like rocks, sand, and plants. It's like a big moving truck that picks up things as it goes along. This is called sediment.
The Churchill River is very special because it has a lot of twists and turns, like a rollercoaster ride. Sometimes it gets wider and sometimes it gets narrower. When it gets wider, it's like the river is taking a break and slowing down because there is more space for the water to spread out.
Along the river, there are also very big forests and lots of different animals that call this place home. It's like a big playground for all the animals to live and play. Some of the animals you might find there are bears, beavers, and birds.
Finally, after traveling for a long time, the river reaches the Atlantic Ocean. It's like reaching the finish line of a race. When the river mixes with the ocean, they become one big body of water. This is where the journey of the Churchill River comes to an end and it gets to rest in the big, wide ocean.
