Sophia - Environmental Science - Unit 1 Challenge 2.
1 — Earth's Formation: History of Earth's Formation
Determine the date of major events for Earth's history, according to the one-year calendar
model.
According to the one-year calendar model based on the Big Bang theory, which of
the following events happened in September?
a.) The solar system comes into existence.
b.) The Big Bang occurs.
c.) Life appears on Earth.
d.) Homo sapiens appear on Earth.
2 — Earth's Formation: Atmosphere Conditions
Differentiate between the conditions in the atmosphere before and after life formed on Earth.
Some early life forms developed photosynthesis, which released free oxygen.
When oxygen is impacted by UV radiation, it forms __________.
a.) ozone
b.) water
c.) oxygen
d.) sulfur dioxide
3 — Early Life
Identify challenges for plant and animal life adapting to land.
Which of the following was a challenge for plants and animals when adapting to
life on land?
a.) Moving around without water for transportation
b.) Receiving enough radiation to maintain temperature
c.) Experiencing too much ozone
d.) Absorbing carbon dioxide from the atmosphere
4 — Continental Drift and Major Extinctions: Tectonic
Plates
Recognize the relationship between tectonic plates and continents according to the theory of
continental drift.
