Self-study
Support The more sunlight our planet reflects back into space, the cooler the global atmosphere tends to become. ████ ███ ███ ███████ ████ ████ ████████ ████ ████ █████ ████ ██ █████ █████ ██ ████ ███████ ████ ██████ ██████████ ███ ███████ ███ ████ ██ ███████ ███████ ████ ██ ███████ ████ ████ ███ ████ ███ ███████ ██ ████████ ███ ██████ ██████████ ██ ██████ ██ ███████
Summarize Argument
The author concludes that if more of Earth’s surface area is covered with snow and ice, the global atmosphere will probably become cooler. This is supported by the observations that snow and ice reflect more sunlight into space than ocean or land, and the atmosphere becomes cooler when more sunlight is reflected into space.
Notable Assumptions
The author assumes that increased snow and ice coverage on Earth will not have other effects that counteract the cooling caused by greater sunlight reflection.
