For keyboard navigation, use the up/down arrow keys to select an answer. a Mars has 1% of Earth's atmosphere and has huge dust storms b Mars has a surface geosphere made of solid iron & evidence of plate tectonics с Mars poles are -220 degrees farenheit and have H2O +CO2 ice caps with glaciers and glacially carved geosphere topography d Mars summer equatorial temperatures are 70 degrees farenheit e Mars must have had a magnetic field or it couldn't have had a surface H20 hydrosphere f Mars has weaker gravity & less predictable weather, & higher UV radiations g Scientists think that single-celled life could have lived in Mars surface waters and are searching for paleo-proxy records of an ancient Mars biosphere

Which one of the following is NOT true of life in our solar system? Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. a Mars may have had a biosphere more than 3 billion years ago but there is no surface biosphere today b Titan may have life in a liquid geosphere layer made of geothermally heated water trapped beneath the solid crust C Titan has a surface geosphere of water ice and liquid hydrosphere of methane with a thick sun dimming atmosphere that is influenced by geosphere outgassing (cryo-volcanism) d If we were to search for living things on Titan we would need to send submersibles into unknown methane seas e Earth is the only world with a complex surface biosphere and a climate suitable to the stability of the biosphere We have direct evidence of alien life existing on another world I Full

Every aspect of nature contributes to and influences climate, so the climate is the current state of dynamic equilibrium or disequilibrium on a world. A biosphere can only live within the parameters that it has adapted to, and the only Earth biosphere- friendly climate we know of is Earth. Select an answer and submit.
