Question

vocabulary: match the vocabulary word to its definition.
answer vocabulary: air and water

1. pollution
2. desertification
3. urbanization
4. changing the flow of water
5. deforestation
6. erosion

definition:
a. cutting down forests for farming, building, or making products. this can cause soil to wash away and make the climate warmer.
b. building cities and roads where there used to be nature. it can make it harder for animals to find homes and clean water.
c. turning fertile land into dry, barren desert. it makes it harder for plants to grow, animals to find food, and can lead to big dust storms.
d. when soil gets washed or blown away because of things like farming or not having enough plants. it can cause floods and harm habitats.
e. making the air and water dirty with things like smoke from factories and chemicals. it can make land less useful for growing crops, cause floods, and harm fish in rivers and oceans.
f. building dams and changing rivers paths. it can make people and animals sick (e.g., pesticides from farms). it can sometimes make floods or droughts worse.
directions: read each scenario. decide which type of human impact is being described. choose from deforestation, urbanization, desertification, erosion, the human impact

1. a forest is cleared to make space for farmland.
2. a city expands into nearby wetlands, replacing natural areas with roads and buildings.
3. a hillside loses all its trees due to logging. heavy rains wash away the soil and nearby rivers become muddy.
4. animals lose their habitat and traffic increases as a new shopping center is built in a region that once had healthy grasslands.
5. rainwater runs off quickly, causing flooding and erosion in the area. over time, the land becomes desert - like.
6. a dry area is farmed without rotating crops or adding nutrients. the land turns to sand and wildlife disappears.
7. a neighborhood is built down to the waters edge in a tropical forest. the temperature in the area rises and there is no rain for a long time.
8. a tropical forest is cut down to build roads and houses. the soil care is poor and land management is bad. after years, the land turns into desert.

Explanation:

1. Air and Water Pollution: La descripción de humos y químicos de fábricas que afectan a ríos, océanos y causan daño a plantas y animales se ajusta a la contaminación del aire y el agua.
2. Desertification: La idea de que el suelo se vuelva árido y no apto para la vida vegetal o animal se asocia con la desertificación.
3. Urbanization: La construcción de ciudades y carreteras, y el hecho de que se utilice el suelo para edificios en lugar de para la naturaleza se asocia con la urbanización.
4. Changing the Flow of Water: La construcción de represas y la alteración de los ríos se asocian con el cambio en el flujo del agua.
5. Deforestation: La tala de bosques y cómo afecta a los animales que viven en ellos se asocia con la deforestación.
6. Erosion: La descripción de cómo las lluvias fuertes lavan el suelo y los ríos se vuelven fangosos se asocia con la erosión.
