10. Climate

11. EFFECT OF CLIMATE AND WEATHER ON ECONOMY AND LIFE
Natural disasters cause problems for humans, animals, and businesses.
Tornadoes cause damage to livestock and property by high winds.
Droughts cause water shortages and damage Texas farm and ranching industries.
Hurricanes, floods, and blizzards injure people and damage property and industries.

12. The Texas Climate Region Characteristics Cause/Reason all regions
Rio Grande valley;
north-central Texas
Gulf Coast
Panhandle
West Texas
hot summers;
lots of sunshine
closeness of Texas to equator
rainfall increases west to east
warm, moist Gulf air in East Texas
hotter temperatures
warm, dry winds from the west
cooler summers;
warmer winters; higher humidity
sea breezes off the Gulf of Mexico
colder in winter; has northers
cold winds from the north
cooler at higher elevations year-round
at higher elevations air is thinner and absorbs less heat

13. PLANTS AND ANIMALS ARE AFFECTED BY LANDSCAPE AND CLIMATE
Climate, landforms, and soil determine where a plant will grow.
Vegetation provides a habitat to a wide variety of animals.
- habitat – environmental home

14. Population

15. FACTORS THAT HAVE LED TO POPULATION GROWTH IN TEXAS
More births and fewer deaths
Increased immigration and migration
Population Growth Rate

16. GROWING TEXAS POPULATION
Texans and Geography
GROWING TEXAS POPULATION
immigration and migration
birth rate higher than death rate
decreasing death rate due to better health care
