In ocean waves, water particles move ________ and energy moves ________. A) vertically; in circles B) in circles; horizontally C
son4ous [18]
In ocean waves, water particles move in circles and energy moves horizontally. Ocean waves are orbital progressive waves. The water molecules that make up the wave move in circles, or orbits, as the wave progresses. The ocean orbital waves get their start when wind blows on the open ocean, A gentle wind doesn't have much of an effect, but the stronger wind becomes the more it pushes against the water. It transfers energy to the water as it makes peaks and whitecaps in the water's surface.

The____ is the section of the rainforest that is too dark for most plant life.(write response, no opinion choices)
AveGali [126]

Answer:

Forest floor

Explanation:

Tropical rainforest is characterized by high rainfall that allows a diverse growth of plant species. The different species of plants and animals species that make up a rainforest are found in different layers. There are four layers or sections in the rainforest from top to bottom viz: emergent layer, canopy, understory and forest floor.

Since the layers are classified from top to bottom, each layer receives different amount of rainfall and sunlight. According to the question, the FOREST FLOOR receives the least amount of sunlight making it the darkest section of the rainforest. Due to the inhibited penetration of sunlight into this layer, it usually does not support any plant growth.
