are mostly trapped. (3) The heat doesn't radiate back into the atmosphere because it's held in
by the glass. (4) Something like that happens on Earth. (5) The atmosphere acts like a blanket

2. This question is based on the following passage.
Both Seagulls and wild geese are large birds. They're also similar in that both kinds of birds
can fly over great distances. On the other hand, seagulls are scavengers, while wild geese
aren't. Seagulls, for example, are often found around garbage dumps. Geese, however, feed
on things like seeds and insects. Another important difference between the two kinds of birds
is that geese fly on long annual migrations of well over 1,000 miles. Seagulls will migrate far
inland to search for food. However, they don't follow seasonal patterns of migration like wild
geese.
