Earth and Outer Space Bookmarks Bundle

These three bookmarks for Earth science and space lovers make a fantastic trio of reference tools for home reading or fieldwork.

Item 1 - Geologic Timescale Bookmark:
This bookmark shows the divisions of geologic time to scale, without distorting the relative duration of each division. The front side breaks down the eons and eras of Earth's history from the present back to coalescing cloud of dust. The reverse side is a close-up of the most recent eon of Earth time (the Phanerozoic) zoomed down into eras, periods, and epochs.

Item 2 - Layers of the Earth Bookmark:
From outer atmosphere to inner core, this bookmark visualizes all the major layers of the Earth relative to our location at the surface. The front side provides a cross section of the Earth and atmosphere with each layer drawn to scale. On the reverse, the surface of the Earth is detailed from the top of Mt Everest to the depths of the Mariana Trench, with each layer of the ocean labeled for reference.

Item 3 - Scale of the Solar System Bookmark:
Put the immensity of our galactic neighborhood into fresh perspective with this bookmark. The front side visualizes the relative scale of solar objects — the Sun, planets, major moons, and asteroids. On the reverse, two scales show the distance of planets and asteroids from the Sun. It's a whole lot of space in a tiny package!

Water and tear resistant coating makes this bookmark durable and ready for fieldwork.
