Question 1

What are tectonic plates?

Accepted Answer

Tectonic plates are big pieces of the Earth's outer layer that fit together like a puzzle. They are always moving, but very slowly, kind of like how a snail moves.

Question 2

How many tectonic plates are there?

Accepted Answer

There are seven big plates and many smaller ones. Some of the big ones include the Pacific Plate and the North American Plate.

Question 3

Why do tectonic plates move?

Accepted Answer

Tectonic plates move because the Earth’s insides are hot and create a flow underneath them. This flow pushes the plates around.

Question 4

What happens when tectonic plates move?

Accepted Answer

When tectonic plates move, they can cause earthquakes, make mountains, and even create volcanoes. It all depends on how the plates are moving.

Question 5

What is an earthquake?

Accepted Answer

An earthquake is when the ground shakes because two tectonic plates are slipping or sliding past each other. It's like when you try to snap your fingers and the friction causes a pop.

Question 6

What is a volcano?

Accepted Answer

A volcano is a mountain that can let hot, melted rock called lava come out. This usually happens when tectonic plates have gaps or holes between them.

Question 7

How are mountains formed?

Accepted Answer

Mountains are formed when tectonic plates crash into each other and push the ground upwards. It's a bit like when you push two ends of a crumpled paper together and a bump forms.

Question 8

What is the Earth’s crust?

Accepted Answer

The Earth’s crust is the outermost layer of our planet. It’s like the thin skin of an apple and it’s where tectonic plates are found.

Question 9

Who discovered tectonic plates?

Accepted Answer

A scientist named Alfred Wegener came up with the idea of tectonic plates in the early 1900s. He noticed that continents looked like they could fit together like puzzle pieces.

Question 10

Are tectonic plates always moving?

Accepted Answer

Yes, tectonic plates are always moving, but very slowly. Some plates move as fast as your fingernails grow!

Question 11

What is Pangea?

Accepted Answer

Pangea was a supercontinent that existed when all the continents were joined together. Over millions of years, it broke apart to form the continents we have today.

Question 12

Can we see tectonic plates moving?

Accepted Answer

We can't see tectonic plates moving because they move too slowly. But scientists use special tools to measure their movements over time.

Question 13

How do scientists study tectonic plates?

Accepted Answer

Scientists study plates using tools like seismographs to record earthquakes and satellites to track their movements. They also study rocks and fossils that tell stories of past plate movements.

Question 14

What’s the Ring of Fire?

Accepted Answer

The Ring of Fire is an area around the Pacific Ocean where lots of volcanoes and earthquakes happen. It's like a giant ring of fiery activity!

Question 15

What is a plate boundary?

Accepted Answer

A plate boundary is where two tectonic plates meet. These are important places because they are often where earthquakes and volcanoes occur.

Question 16

Why do earthquakes happen mostly at plate boundaries?

Accepted Answer

Earthquakes often happen at plate boundaries because that's where plates bump, slide, or pull apart from each other. The movement causes the ground to shake.

Question 17

How do volcanoes erupt?

Accepted Answer

Volcanoes erupt when pressure builds up from hot, melted rock under the Earth’s crust. The pressure pushes the melted rock up through cracks until it bursts out.

Question 18

What are underwater mountains?

Accepted Answer

Underwater mountains, called mid-ocean ridges, are formed by tectonic plates pulling apart under the ocean. New rock forms in the gap, creating mountains.

Question 19

Why is tectonic plate movement important?

Accepted Answer

Tectonic plate movement is important because it shapes our planet's surface. It creates mountains, oceans, and can even affect the climate over time.

Question 20

What can people do to stay safe from earthquakes?

Accepted Answer

People can stay safe by building strong structures, having emergency kits, and practicing safety drills. It's important to know how to 'Drop, Cover, and Hold On' during an earthquake.
