Question

how are deserts and tundras simliar? they both receive up to 25 cm of precipitation each year, they both are home to different types of cacti, they both have temperatures that reach 120 F, they both have a top layer of permafrost

Answer 1

Short answer: only the first statement is generally correct.

Details:
- "They both receive up to 25 cm of precipitation each year." — True (both are low‑precipitation biomes; tundra and many deserts typically get on the order of 10–25 cm/year).
- "They both are home to different types of cacti." — False. Cacti are adapted to hot, dry deserts. Tundra plants are low‑growing mosses, lichens, sedges and small shrubs, not cacti.
- "They both have temperatures that reach 120°F." — False. Hot deserts can reach ~120°F (49°C). Tundras are cold; summer highs are usually well below that.
- "They both have a top layer of permafrost." — False as a general statement. Tundra commonly has permafrost (a permanently frozen layer). Most warm deserts do not. Note: some cold “polar deserts” (Arctic/Antarctic) are both deserts and have permafrost, but that’s a special case.

Other true similarities: both have sparse vegetation, low primary productivity, harsh conditions that require special plant/animal adaptations, and fragile ecosystems.
