A) How do greenhouse gases such as carbon dioxide cause global warming? b) What is an "extreme event?

c) Global warming of 1.8°F (1°C) seems small, given that some locations experience temperature swings of 30°F or more in a single day. Why is this change in global temperature a concern?

the damaging of the ozone layer, some extreme events are deadly hurricanes,increases of flooding and more forest fires

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.

this could be newton#'s law of cooling. the cooling curve is exponential
