Life on Earth Trivia Quiz

Answer: Conditions weren't good enough

Nothing lived on Earth for the first billion years of the planet's existence. The conditions were not right for life. There were no plants or animals of any kind. At the time, Earth was a dangerous place where life could not survive.

Answer: Magma underneath the Earth's crust

The continents move about one and a half inches a year - about the length of your pinkie. Millions of years in the future, Earth will look very different from today.

Answer: In the ocean

Life on Earth began about 3.5 billion years ago. It was born into a world that looked very different to today. The atmosphere was filled with poisonous gases, the sky was pink, and the sea was rusty red.

Answer: Crescent

First it looks like a banana (thin crescent), then a sideways laugh (wider crescent, for some areas), then a circle, then it does this all all over again but backwards!

Answer: No

The Earth is not flat. Early explorers thought it was though! They thought if they sailed too far, they would fall off the edge. It was up until Galileo Galilei found this out. He also found out that the Earth wasn't at the center of the universe.

Answer: Responding to your Environment

Some other characteristics of life are: waste production (metabolism), growth, and reproduction. Wondering why I chose response to environment? Living things flinch, get scared, or get hurt. When you touch a cactus and get pricked, you are responding by pulling your hand away. Non-living things won't do this. Have you ever jumped when you got scared? That is your body responding to the "scary" thing.

Answer: Jawless fish

Instead of jaws to open and close their mouths the very first fish sucked food into their mouths. They are called jawless fish. They looked like they had just sucked on a lemon!

The Atlantic Ocean can be bitterly cold...but think about the Arctic Ocean! Did you know the luxury ship Titanic sank in the Atlantic Ocean in 1912?

Answer: False

About 440 million years ago, the first life appeared in the ocean. It was simple plant life, similar to today's mosses. Then, about 400 million years ago, the first land animals - worms, spiders, scorpions and insects - evolved as they moved onto land, then came the dinosaurs.

Answer: True

A black hole is a star that has been incredibly compressed to the point where it collapses under its own gravity. The atoms get squeezed together, so it's a bit like taking snow and squishing it until it turns into hard ice. One teaspoon of a black hole would weigh about 10 tonnes, and gravity is so strong that light cannot escape. That's why they're black.
