Maybe you are referring to crepuscular rays? http://en.wikipedia.org/wiki/Crepuscular_rays
AnswerAphotic Zone or 'Midnight' Zone.No Sunlight Reaches the Layer of Oceanreferred to as the Aphotic Zone or 'Midnight' Zone- this is at Ocean Depths of 1000+ Meters. The Aphotic Zone (sometimes called the 'Midnight' Zone), exists at depths below 1000 meters. No Sunlight Reaches this Zone at all, it is completely absent of light; hence the slang term for it, the 'Midnight' Zone.Detailed ExplanationOceans consist of 3 Zones, the Zones are classified by the amount of Light that passes through. The top two Ocean layers allow for Sunlight to penetrate through, however NOT the Third & Deepest Ocean Layer.Euphotic Zone or 'Sunlight' Zone - Depth 200 Meters:The top most 200 meters of ocean is called the Euphotic Zone (or called the 'Sunlight' Zone). Sunlight travels easily through this Zone of the Ocean and plant-life is widespread.Dysphotic Zone or 'Twilight' Zone - Depth 200 Meters - 1000 Meters:This layer, immediately beneath the Euphotic Zone/'Sunlight' Zone, between 200 meters and 1000 meters is called the Dysphotic Zone (or more commonly called the 'Twilight' Zone). Sunlight dissipates quickly as the depth increases, and very little light penetrates throughout this, Dysphotic Zone.Aphotic Zone or 'Midnight' Zone - Depth 1000+ Meters:The Aphotic Zone (sometimes called the 'Midnight' Zone), exists at depths below 1000 meters. No Sunlight Reaches this Zone at all, it is completely absent of light; hence the slang term for it - 'Midnight' Zone.
Jupiter is called Jupiter because he is the God of all Romans and sunlight
Through Photosynthesis.The plant absorbs the energy from sunlight using mall organelles (organs of a plant cell) called chloroplast witch capture light energy and uses it to combine the carbon dioxide and water molecules to make food and oxygen as a waste product. formula for it is 6H2O+6Co2 Direct sunlight =C6H12O6 (Glucose witch is used as food) +6O2
oculus
New Moon
The opening in the eye which allows light to pass through is called the pupil.
These opening are called pores.
Precipitation seeping through cracks and holes in the ground.
through a process called photosynthesis.
convention
A Crevasse
The opening in called a urethra, in both males and females.
Photosynthesis
A volcano is the opening called in the earths crust called through which lava gases and other pieces of rock erupt.
Limestone caves are sometimes called solution caves because they are formed through a process called solution weathering. This occurs when water containing carbon dioxide dissolves the limestone rock, creating cave systems over time. The dissolved limestone is carried away in the form of a solution, hence the term "solution cave."
the process of seeping of water into the ground is called infilteration
Sunlight can penetrate through the limnetic zone into the profundal zone.
