What are earthquakes?

Earthquakes feel like a huge shake to the land. If we are in a classroom, the desks might move and bang about. Earthquakes can make cracks in walls, tip over food in a grocery store aisle, or even cause a building to fall down.

How do earthquakes work?

There are some excellent sites that have information about how earthquakes work.

DKFindOut!

DKFindOut! has great illustrations to help us understand what is happening under the earth and on top of it during an earthquake.

• Search using the keyword 'earthquake'.
• This brings up a range of pages with information about earthquakes such as How plates move, What causes an earthquake etc.

Tips: Search words, or keywords, are the most important words in our question. Usually it’s better to leave out small words like ‘the’, ‘a’ and ‘of’ and just choose the main ones, e.g [earthquakes]. We can always change our keywords or add more if we need to.

This is one of the EPIC resources. EPIC is a collection of reliable databases covering lots of different topics. It’s put together especially for New Zealand school students and helps to answer questions like this.
