The Red Planet Mars
Read the two short stories with a helper, then answer the 5 questions.
Reading Passage
Mars is a neighbor planet in space. It is right next to planet Earth. Mars looks red because it has red dust and rusty rocks all over the ground. People call it the Red Planet .
Mars is very cold and dry. It has big red hills and rocks. People cannot walk on Mars yet, but friendly robot rovers roll on the ground. These rovers take photos and send them back home to us!

The Mysterious Red Planet
Informational Text Homework
Read both paragraphs carefully, then answer questions 1–5 using information from the text.
Mars: Earth's Desert Neighbor
Mars is the fourth planet from the Sun and one of Earth's closest celestial neighbors. Often called the Red Planet, its vivid reddish-orange hue comes from iron oxide—the same mineral compound found in rusty iron—covering its rocks and soil. While its color makes it look blazing hot, Mars is actually a freezing desert. Because it sits farther from the Sun and has a very thin atmosphere, the average temperature is about minus 80 degrees Fahrenheit!
Mars has dramatic landscapes, including Olympus Mons, the largest volcano in the solar system, and canyons deep enough to swallow mountain ranges. Because Mars has almost no oxygen to breathe and liquid water quickly freezes or evaporates, humans cannot survive there without specialized space suits. To explore safely, NASA sends robotic rovers like Curiosity and Perseverance to roll across the terrain, drill into rocks, and search for ancient signs of water.
Comprehension Questions
1. Why does Mars appear reddish-orange from space?
A Lava constantly erupting from volcanoes
B Iron oxide rust covering its soil and rocks
C Flames burning across the Martian desert
D Red sunlight reflected off thick clouds
2. According to the text, what is the climate like on Mars?
A Warm and humid with rainy seasons
B A scorching desert with hot winds
C A freezing desert averaging -80°F
D Mild and tropical like Earth's equator
3. What is Olympus Mons?
A The largest volcano in the solar system
B A robot rover exploring the surface
C A frozen ocean under the Martian soil
D A space suit designed by NASA
4. Explain two reasons why humans cannot survive on Mars without space suits:
5. What tools do scientists use instead of astronauts to explore Mars, and what do they search for?

Geology and Atmosphere of Mars
Informational Text Homework
Read both paragraphs carefully. Then, answer questions 1–5 using text evidence to support your answers.
The Red Planet's Extreme Environment
Mars, often dubbed the Red Planet because iron oxide rust blankets its loose surface regolith, presents one of the most intriguing environments in planetary science. Although a Martian solar day (called a sol) lasts 24 hours and 37 minutes—remarkably close to Earth's—the climate is brutally inhospitable. Mars possesses a tenuous atmosphere composed of roughly 95 percent carbon dioxide, creating surface pressure less than one percent of Earth's. Lacking a protective ozone layer or strong magnetic field, Mars is continuously bombarded by harsh solar radiation, while ferocious global dust storms periodically shroud the entire planet, plunging surface temperatures below minus 125 degrees Celsius.
Despite these harsh conditions, Mars preserves extraordinary clues regarding the evolution of rocky planets. Because geological activity ceased eons ago, monumental formations remain intact, including Olympus Mons, a shield volcano nearly three times higher than Mount Everest, and Valles Marineris, an immense rift canyon system spanning over 2,500 miles. Ancient dry riverbeds, lake basins, and hydrated mineral deposits discovered by NASA rovers prove that liquid water once flowed across the terrain. Today, scientists examine these ancient formations searching for biosignatures—fossilized chemical evidence of microscopic life from when Mars was warm and wet.
Comprehension Questions
1. What gas makes up approximately 95 percent of Mars' thin atmosphere?
A Pure breathable oxygen
B Carbon dioxide
C Nitrogen and hydrogen
D Liquid water vapor
2. Why is the surface of Mars exposed to dangerous levels of solar radiation?
A It is located directly next to the Sun
B It lacks a protective magnetic field & ozone layer
C Huge volcanoes reflect solar rays
D Dust storms generate electrical energy
3. What physical evidence proves that liquid water once flowed across Mars?
A Dry riverbeds, lake basins, & mineral deposits
B Flowing rivers photographed by NASA satellites
C Deep oceans buried under Olympus Mons
D Rain clouds forming over the equator
4. Contrast Olympus Mons and Valles Marineris using specific measurements or details from paragraph 2:
5. According to the text, what are "biosignatures," and why are scientists searching for them?
