This page is meant to model rotation. Each student received a view of the earth from the top. We attached a brad through the north pole and marked which way the earth spins. We added the definitions of rotate, axis and axial tilt. There is also a line showing where day/night meet.---will have to use!!!

Long-term changes in Earth’s axial tilt, or obliquity, is just one factor affecting how much sunlight strikes Earth’s Northern Hemisphere, which influences the coming and going of ice ages. Every 41,000 years or so, Earth’s obliquity ranges from 22.1° to 24.5° and then back again.


Mars Arctic Block Falls Reveal Dynamic World JUN 27, 2014 // BY IAN O'NEILL Around the frigid north pole of Mars, frozen layers of dust and ice have formed, deposited over millions of years as the planet’s climate has waxed and waned in response to Mars’ axial tilt. Now, in new observations beamed back to Earth by the HiRISE camera on board NASA’s Mars Reconnaissance Orbiter (MRO), some of these layers have been spotted that have fragmented and fallen down a slope as a “block fall.”


The Sun or Sol, is the star at the centre of our solar system and is responsible for the Earth’s climate and weather. The Sun is an almost perfect sphere with a difference of just 10km in diameter between the poles and the equator. The average radius of the Sun is 695,508 km (109.2 x that of the Earth) of which 20–25% is the core. Image Credit: SOHO/EIT

A Christmas card for people who don't celebrate the "season" but have a good time anyway. Axial Tilt is the reason for the season
