Climate change on Mars and Earth - Coggle Diagram
Climate change on Mars and Earth
General
Composition
Substantial amount of iron on the surface and in the core
The amount of rock
The planets' chemical
Water
Ice age
Earth: About every 100,000 years
Mars: Recent about 370,000 years ago
Milankovitch cycles
Eccentricity: The changing shape of the planet's orbit around the sun
Obliquity: The tilt toward the sun
Precession: A planet's wobble along its axis
Ice age effects
Earth
Polar freezing
Glacier spread toward equator
Consequences
Global cooling and harsher climate
Sea level drops as water is locked in ice
Ice sheets grow > 12,000 feet thick
Mars
cause poles to warm while mid-latitudes cool.
Ice retreats from poles toward center during warm phases
When tilt straightens,poles freeze again,reversing cycle.
Consequences
erosion paths
buries ground ice
Current climate status
Mars is currently in a warmer interglacial period,similar to Earth's present climate
Evidence from computer models and radar imagery confirms warming.
Importance of research:
Helps scientists understand Earth’s climate cycles more deeply.
Provides insights for future space exploration and human missions to Mars.
Strengthens knowledge of how planetary tilt and orbit shape long-term climate.
