Which of the following is a terrestrial biome?
a. tundra
b. benthic zone
c. estuary

Option (A)

Explanation:

A biome is defined as a biological community where the different types of living species share common characteristics in the environment within which they exist. There are a number of factors that controls a biome and the type of organisms such as temperature, rainfall, humidity, latitude, soil and many more.

It includes both the continental as well as the oceanic region, where a large number of living species exists. The biomes that cover the continental portion (terrestrial areas) are known as the terrestrial biomes. Some of the examples of terrestrial biomes are tundra, grassland, desert and forest biome.

Benthic zone and estuary are a part of the marine biome as it covers a certain part of the ocean.

Thus, the correct answer is an option (A).

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.

d. groundwater flows through the subsoil and deposits minerals.
