Question 10 • DRHS GA-GSE Earth Systems

A large asteroid impact occurs, kicking up dust that blocks the Sun and prevents plants from photosynthesizing. What would most likely happen as a result of the asteroid impact?

Answer
A
More earthquakes would occur across the planet.
B
Some plants would evolve to use dust as a source of food.
C
Many plants would perform photosynthesis without sunlight.
D
Many species would eventually die off because they lack a food source.

Explanation

Plants need sunlight to photosynthesize and make food. If dust blocks the Sun, many plants would die or stop growing, reducing the food available to animals and other organisms. As food chains break down, many species would eventually die off; dust would not replace sunlight or become food for plants.
