When more people live in a city than it can support, living condition deteriorate. This is known as

• urban crisis
• urban sprawl
• urbanization
• infracstructure

People moving from the rural areas to cities is called...

• Ruralization
• Urbanization
• Colonization
• None of these

the urban heat island is most evident

• in rural areas
• in the summer time
• at night

urban areas are often warmer than the surrounding rural areas because

• changes in surface to less reflective ones
• tall building can block wind movement
• increased airconditioner use and low level pollution increase trapped heat
• All of these

What is a "heat island"?

• an island in a river or lake that produces heat
• an area in which the air temperature is generally higher than the temperature of surrounding rural areas
• when the leftovers or "tailings" from mining are piled up in a river
• an oasis

What causes urban heat islands?

• movement of people from farms to cities
• lots and lots of people heating their homes
• roads and buildings absorb and retain heat longer than vegetation does
• soil erosion

What is deforestation?

• throwing someone out of a window
• selectively cutting trees for lumber, making sure the forest remains healthy
• allowing more animals to graze on the land than it can support
• cutting and removal of rainforest

What are some reasons deforestation occurs?

• clearing land for agriculture, ranching, and mining
• just wanting to destroy things
• Population moving from rural areas to cities
• to make room for infrastructure

Soil is made of

• weathered rocks and minerals
• dead plants and animals
• air and water
• all of the above

Areas of open land with few people, homes, and businesses 

• Suburb 
• Urban 
• Rural 
• City
