Compare BETWEEN EARTH AND MARS

 ATMOSPHERE:

1- EARTH: EARTH HAS A NITROGEN AND OXYGEN-BASED ATMOSPHERE, WITH TRACES OF OTHER GASES SUCH AS CARBON DIOXIDE, WATER VAPOR, AND OTHER GASES.

- MARS: MARS HAS A MUCH THINNER ATMOSPHERE CONSISTING MAINLY OF CARBON DIOXIDE (OVER 95%), WITH TRACES OF NITROGEN, ARGON, AND OXYGEN.

2. AXIAL TILT:

- EARTH: EARTH HAS AN AXIS TILT OF 23.5 DEGREES WHICH CAUSES THE CHANGE IN SEASONS.

- MARS: MARS HAS A SIMILAR AXIS TILT TO EARTH, WITH ABOUT 25 DEGREES. 

THIS ALSO RESULTS IN SEASONAL VARIATIONS ON MARS.

3. LENGTH OF DAY:

- EARTH: EARTH'S ROTATION PERIOD, OR LENGTH OF DAY, IS 24 HOURS.

- MARS: MARS HAS A LONGER ROTATION PERIOD, WITH A DAY LASTING APPROXIMATELY 24 HOURS AND 37 MINUTES.

4. LENGTH OF YEAR:

- EARTH: EARTH TAKES ABOUT 365.25 DAYS TO COMPLETE ONE ORBIT AROUND THE SUN, RESULTING IN A YEAR.

- MARS: MARS HAS A LONGER YEAR COMPARED TO EARTH. IT TAKES APPROXIMATELY 687 EARTH DAYS (OR 1.88 EARTH YEARS) TO COMPLETE ONE ORBIT AROUND THE SUN.

5. SURFACE :

- EARTH: EARTH HAS A RANGE OF LANDMASS, INCLUDING OCEANS, CONTINENTS, AND A VARIETY OF ECOSYSTEMS THAT SUPPORT A WIDE ARRAY OF LIFE FORMS.

- MARS: MARS IS A COLD AND DRY PLANET WITH A ROCKY SURFACE. IT LACKS LIQUID WATER ON ITS SURFACE, ALTHOUGH EVIDENCE SUGGESTS THE PRESENCE OF FROZEN WATER IN THE POLAR ICE CAPS AND UNDERGROUND.
