You're listening to Sleep Tight Science. Did you know the world record for the heaviest pumpkin is for a pumpkin that weighed 2,624.6 pounds?

What?

Hello, friends, and welcome back to sleep tight science, a bedtime show that answers the questions you have about science. In this episode, we are going to learn a little bit more about Halloween.

It is pseudoscientific.

Are you ready for Halloween?

What is your favorite part of Halloween? Do you enjoy the trick-or-treating?

In this episode, we are going to find out a little bit about the history of trick-or-treating.

food becoming harder to find is another reason why these creatures seem to be around more in the fall.

Before we get started on our topic, let's look at a couple of questions sent in by our listeners.

How does the world make rocks, and why are they so hard?

This question comes from Maddie in Germany. That's a bit of a tricky question, Maddie, because there are three main types of rocks, igneous, sedimentary, and metamorphic. And each kind is formed

differently. Igneous rocks are formed when melted rock cools into a solid.

This can happen underground or above the ground.

Sedimentary rocks can take millions of years to form.

When soil and surface materials erode or wear away, they leave layers of sediments.

Over long periods of time, layer upon layer of sediments form, and this puts enormous pressure on the oldest layers.
