One student designed an experiment to demonstrate the formation of a geologic feature. The steps of the experiment are listed below. Place a rectangular piece of cardboard on a table.
Take a two inches long rigid broom straw.
Place the straw on the cardboard along one of its edges.
Use a clip to attach the middle of the straw to the cardboard so that approximately half of the straw is on each side of the clip.
Place one hand on each of the two halves of the straw.
Push both ends of the straw towards the clip.
Observe the straw snap as it moves up and bends due to pressure.

Which of these geologic features was created by the process demonstrated by the student's experiment?
the Aleutians Islands
the Big Island of Hawaii
the Grand Canyon
the Sierra Nevada Mountains

it is very hard for the climatologists to precisely predict how will the global temperatures be changing so there's lots of models, some of which differ significantly, this is due to multiple factors, and probably the most important is the human activity.

humans have been a key factor in climate change around the globe since the start of the industrial revolution, and in the past few decades the consequences are becoming more obvious. there's lots of emission of pollutants in the atmosphere as well as changing the environment on the surface itself, so it's really hard to predict how will that go in the future because there's some countries that are reducing the damage and are going towards green energy, while others are stubbornly continuing with pollution and damages to the environment.
