Question

wormformation
earthworms live in many places on earth. some
however, do not provide a suitable environment for them.
you rarely find an earthworm in a desert, high on a mountain, or in areas
constantly under snow and ice. they dont live in oceans-most species
of earthworms cannot tolerate salt water. earthworm species can
spread or migrate from one region to another, but deserts, oceans,
mountain ranges, and glaciers serve as barriers to worm migration.

why?

1. what characteristics of a desert make it an unsuitable

place for an earthworm to live?

1. if an ocean is a barrier to earthworm migration,

how do you think european worm species came to
north america?

1. would you likely find earthworms in lands along the equator? yes □ no□

why?
bonus activity use a globe or world map to locate and list earthworm barri

Explanation:

1. Earthworms cannot tolerate constant snow and ice, which are common in the arctic tundra.
2. Deserts have harsh conditions like extreme heat, lack of moisture, and poor soil quality that are unsuitable for earthworms.
3. European worm species might have come to North America through human activities such as transportation of plants, soil, or other materials.
4. Yes, because lands along the equator generally have suitable environmental conditions (like moisture and soil quality) for earthworms.

Answer:

1. no. Because earthworms cannot tolerate constant snow and ice which are present in the arctic tundra.
2. Deserts have extreme heat, lack of moisture, and poor soil quality (unsuitable environment characteristics).
3. Through human - related transportation (e.g., of plants, soil).
4. yes. Because lands along the equator usually have suitable environmental conditions (like proper moisture and soil) for earthworms.
