What are interglacial periods?

The Earth sometimes takes long vacations, these are called interglacial periods.

Imagine your favorite toy is a giant ice cube that covers most of the planet. When it's on, we're in an ice age. But every once in a while, this ice cube starts to melt, and the Earth gets warmer, like when you take your ice cream out of the freezer on a hot day.

This warm time is what we call an interglacial period, and it's when life gets more comfortable for plants, animals, and people. Right now, we're in one of these warm times!

These Earth vacations usually last about 10,000 to 20,000 years, that’s like having a summer break every few centuries! During this time, the planet is mostly green and friendly, with fewer icebergs around.

It's all because of how the Earth spins and tilts. Sometimes our planet leans in a way that lets more sunlight reach us, making it warmer, just like when you stand closer to a fire. The Earth sometimes takes long vacations, these are called interglacial periods.
