A definition and 5 facts worth remembering.
The only planet known to have liquid water on its surface, and the only one known to have life.
- 71% of the surface is covered by ocean.
- The atmosphere is mostly nitrogen, with 21% oxygen.
- The magnetic field shields us from solar radiation.
- Tilted 23.5°, which is what gives us seasons.
- The Moon's pull creates our tides.
- Order — 3rd
- Day — 24 hours
- Year — 365.25 days
- Moons — 1
- Look down.
A "day" is one spin. A "year" is one trip round the Sun. On Earth they are nothing like ours.

- Who is the Earth poster for?
- Earth is filed under 4th Grade (ages 9–10), so it matches what that year asks a child to remember. It is equally useful to an older student revisiting science, and to the parent or teacher answering the question at the kitchen table.
- When should you use the Earth poster?
- Look down. A wall chart earns its place by being glanceable from where the work is happening, so Earth belongs on the wall where that science work actually happens, within glancing distance, rather than filed away.
- What other posters go with Earth?
- Jupiter, Mars and Mercury sit alongside Earth in the 4th Grade set. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.JupiterMarsMercury
- Is the Earth poster free to download and print?
- Yes. Earth downloads as a free PDF with no account, no email and no watermark, like everything else in the 4th Grade set. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Earth poster print at?
- Earth is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Earth loses nothing.Printing guide
