Cracks in rocks widen as water in them freezes and thaws. How does this affect the surface of the Earth?
It reduces the rates of soil formation.
It changes the chemical composition of the rocks. .
It exposes rocks to increased rates of erosion and weathering

Urban City X has been referred to as an urban heat island because it tends to be warmer than the surrounding rural areas. The report below lists changes that have occurred in one year in Urban City X.
Report for Urban City X:
• Eight roads were repaved.
• The population increased by 20%.
• Public transportation increased by 5%.
• Four new apartment complexes were built.
• Plans were drafted to build a local park.
• A meeting was held about alternative energy sources.
What is the main cause of Urban City X being an urban heat island?

How does the tilt of the Earth’s axis affect the seasons?
by changing the amount of direct solar energy reaching the surface of Earth
by influencing the rate of chemical reactions occurring in the atmosphere
by deflecting the harmful rays of radiation emitted by the sun
by changing the speed of the rotation of Earth
How could the introduction of a nonnative species of plant affect an ecosystem in North Carolina?
It could pollinate the native plant species, producing a disease-resistant species.
