Question 1

What is the role of oceans in Earth's climate?

Accepted Answer

Oceans help keep our planet's weather and temperature in balance. They store and slowly release heat, which makes temperatures less extreme.

Question 2

Why are oceans important for weather patterns?

Accepted Answer

Oceans help create weather by exchanging heat and moisture with the air. This can lead to rain, clouds, and winds that we experience.

Question 3

How do oceans affect the temperature on Earth?

Accepted Answer

Oceans absorb sunlight and heat up, then slowly release this heat. This helps keep our planet's temperature not too hot or too cold.

Question 4

What is an ocean current?

Accepted Answer

An ocean current is like a river of water flowing through the ocean. These currents move warm and cold water around the Earth, affecting climates.

Question 5

How do ocean currents impact the climate?

Accepted Answer

Ocean currents carry warm water to cold places and cold water to warm places. This helps make weather milder and influences climate all over the world.

Question 6

Why is the ocean called the planet's 'heat sink'?

Accepted Answer

The ocean is called a 'heat sink' because it can take in and store a lot of heat from the sun. This keeps the Earth from getting too hot too quickly.

Question 7

How do oceans help with the water cycle?

Accepted Answer

Oceans are where most of our planet's evaporation happens. When water from the ocean turns into vapor, it helps form clouds and eventually rain.

Question 8

What is evaporation and how does it relate to oceans?

Accepted Answer

Evaporation is when water changes from liquid to gas and rises into the air. Oceans have a lot of water that evaporates, helping to form clouds and rain.

Question 9

Why is ocean water salty?

Accepted Answer

Ocean water is salty because it has minerals and salts from rocks and the Earth's surface. Rivers carry these minerals to the ocean, and they build up over time.

Question 10

How do oceans absorb carbon dioxide?

Accepted Answer

Oceans take in carbon dioxide from the air, which helps reduce this gas in our atmosphere. This process is important because it can help slow down climate change.

Question 11

What happens if the oceans were not there to absorb heat?

Accepted Answer

Without oceans, the Earth would have more extreme temperatures. It would be much hotter during the day and much colder at night, making it harder for life to survive.

Question 12

How do oceans impact animals and plants on Earth?

Accepted Answer

Oceans provide a home and food for lots of animals and plants. They also help make the climate stable, which is important for animals and plants on land too.

Question 13

What is the Gulf Stream and what does it do?

Accepted Answer

The Gulf Stream is a warm ocean current that flows from the Gulf of Mexico up the Atlantic Ocean. It helps warm the climate of nearby countries, like parts of Europe.

Question 14

How do oceans help support life?

Accepted Answer

Oceans are full of tiny plants that make oxygen, which we need to breathe. They also provide food and are a big part of the water cycle, which all living things rely on.

Question 15

Why are coral reefs important to the ocean?

Accepted Answer

Coral reefs are like underwater cities that provide food and shelter for many sea creatures. They also help protect coastlines from big waves and storms.

Question 16

What can happen if ocean temperatures get too high?

Accepted Answer

If ocean temperatures get too high, it can harm sea life like coral reefs. It also affects weather patterns and can lead to stronger storms.

Question 17

How does the ocean help balance the Earth's climate?

Accepted Answer

The ocean absorbs CO2 and heat, keeping temperatures steady. Its currents move heat around, helping to keep climates balanced.

Question 18

What is the biggest ocean on Earth?

Accepted Answer

The biggest ocean on Earth is the Pacific Ocean. It's so big that it covers more space than all the land on Earth combined!

Question 19

How does global warming affect the ocean?

Accepted Answer

Global warming makes the ocean warmer, which can harm animals and plants. It also causes ice to melt, leading to higher sea levels.

Question 20

What are waves and how are they formed in the ocean?

Accepted Answer

Waves are formed in the ocean by winds blowing across the surface. They are like ripples that travel across the water, sometimes getting big enough to surf on!
