Into the Abyss Lesson 1 Review

Front

What is absorption in the context of light?

Back

Absorption is the process by which light waves are taken in by a material, rather than being reflected or transmitted.

Front

What does it mean for light to be refracted?

Back

Refraction is the bending of light as it passes from one medium to another, changing its speed.

Front

Define the euphotic zone of the ocean.

Back

The euphotic zone is the layer of the ocean closest to the surface where sunlight penetrates, allowing photosynthesis to occur.

Front

What is the aphotic zone of the ocean?

Back

The aphotic zone is the layer of the ocean that receives no sunlight, making it dark and inhospitable for photosynthesis.

Front

How do mirrors work in terms of light?

Back

Mirrors reflect light waves, allowing us to see images of objects placed in front of them.

Front

What is the significance of the euphotic zone for marine life?

Back

The euphotic zone is crucial for marine life as it supports photosynthetic organisms, which are the base of the ocean food web.

Front

Explain the concept of light reflection.

Back

Light reflection occurs when light waves bounce off a surface, allowing us to see the object that is reflecting the light.

Front

What happens to light in the aphotic zone?

Back

In the aphotic zone, light does not penetrate, resulting in complete darkness and limiting the types of organisms that can survive there.

Front

Describe the role of light in photosynthesis.

Back

Light is essential for photosynthesis as it provides the energy needed for plants and algae to convert carbon dioxide and water into glucose and oxygen.

Front

What is the difference between the euphotic and aphotic zones?

Back

The euphotic zone is lighted and supports life, while the aphotic zone is dark and does not support photosynthesis.
