What is the planet Mars like? We know a little bit about Mars, although there is much to find out. There are craters and canyons, dunes and volcanoes. The southern part of Mars has many more craters than the northern part.
A year on Mars is equivalent to 687 Earth days.
The atmosphere is mostly made up of carbon dioxide, and the soil is rich in iron, magnesium and calcium.
Mars also has a southern ice cap made of frozen carbon dioxide. It has other patches of frozen carbon dioxide on the planet during Martian winters. Its northern ice cap is made of frozen water.
How can I grow bananas? Do they have seeds? Those little black things at the centre of the banana are seeds. The only problem is, they are sterile seeds, which means they will not produce any bananas.
In order to grow more bananas, you have to plant a runner, or 'sucker', as it is called. The sucker is cut from a growth the banana stalk puts out.
