Question

living things need many things to thrive. life as we know it needs clean water, shelter, air, and food. which of the following characteristics of earth affect earth’s ability to support life? select 4 correct answers.
□ rate of rotation
□ proximity to the sun
□ location in the galaxy
□ presence of liquid water
□ composition of atmosphere

Explanation:

1. Proximity to the sun: Earth's distance from the sun (the "Goldilocks zone") allows for a temperature range suitable for liquid water and life processes.
2. Presence of liquid water: Water is essential for life as we know it, for biochemical reactions, transport, and habitat.
3. Composition of atmosphere: Earth's atmosphere (with oxygen, nitrogen, and greenhouse gases) provides air for respiration, protects from radiation, and regulates temperature.
4. Rate of rotation: Earth's rotation (24 - hour day) helps regulate temperature (prevents extreme heating/cooling) and creates day - night cycles important for life rhythms.
5. Location in the galaxy: Earth is in a relatively safe region of the Milky Way (not too close to the center with high radiation, nor too far with low heavy - element availability), but among the options, the first four are more directly related to Earth's ability to support life compared to location in the galaxy which is a more broad and less direct factor for this question's context. So the four correct ones are rate of rotation, proximity to the sun, presence of liquid water, composition of atmosphere.

Answer:

• rate of rotation
• proximity to the sun
• presence of liquid water
• composition of atmosphere
