Question

Which soil would most likely be found in the Arctic? a. Andisols b. Gelisols c. Histosols d. Spodosols Which gas is most abundant in Earth's atmosphere? a. Oxygen b. Nitrogen c. Water vapor d. Carbon dioxide

Answer 1

1. Gelisols are the most likely soil type found in the Arctic due to the presence of p.e.r.m.a.f.r.o.s.t. Option B is correct.

2. The most abundant gas in Earth's atmosphere is nitrogen. Option B is correct.

Step-by-step explanation:

1. Soil in the Arctic: Gelisols are characterized by p.e.r.m.a.f.r.o.s.t within 2 meters of the surface, which is common in Arctic regions due to the extremely cold temperatures. Gelisols typically contain permanently frozen ground and are often found in areas with cold climates, such as the Arctic.

2. Abundant Gas in Earth's Atmosphere: Despite oxygen being vital for life, nitrogen comprises approximately 78% of Earth's atmosphere. It dominates the atmospheric composition, followed by oxygen, trace amounts of argon, and other gases. Nitrogen's abundance is due to its inert nature, making it stable and prevalent in the atmosphere.

Gelisols are found in the Arctic due to their p.e.r.m.a.f.r.o.s.t characteristics, while nitrogen is the most abundant gas in the Earth's atmosphere, accounting for around 78% of its composition.

Correct answer:

1. b. Gelisols
2. b. Nitrogen
