Answer: Sun, clouds, vegetation or plants, little wind, Hill.
Explanation:Riding on my bike,towards the top of the hill, I know water cycle is happening, this is evident first from the SUN which had risen in the morning, heats up the LAKES ( water body ) while also providing energy for PLANTS which gives off water vapor through transpiration. That vapor then evaporates to atmosphere to form bright CLOUDS. because it is a warm summer day , there is less WIND which does not move the clouds to form rain. The big gulp of COLD WATER I saw on the HILL should be from the result of accumulated rain water. This will gradually infiltrates into the GROUND to return to the ocean. And thus cycle continues.
The water cycle, therefore is a continuous movement of water on every part of the surface of the Earth by processes of evaporation, condensation, precipitation, infiltration, surface runoff, and subsurface flow through different forms of liquid, solid (ice) and vapor.
Refraction is an effect that occurs when a light wave, incident at an angle away from the normal, passes a boundary from one medium into another in which there is a change in velocity of the light. Light is refracted when it crosses the interface from air into glass in which it moves more slowly. Since the light speed changes at the interface, the wavelength of the light must change, too. The wavelength decreases as the light enters the medium and the light wave changes direction. We illustrate this concept in Figure 3 by representing incident light as parallel waves with a uniform wavelength . As the light enters the glass the wavelength changes to a smaller value '. Wave "a" passes the air/glass interface and slows down before b, c, or d arrive at the interface. The break in the wave-front intersecting the interface occurs when waves "a" and "b" have entered the glass, slowed down and changed direction. At the next wave-front in the glass, all four waves are now traveling with the same velocity and wavelength
Answer:
d. occur in the same place, the cytoplasm
plant growth
animal actions
pressure release
Explanation:
The causes of mechanical weathering of rocks include plant growth, animal actions and pressure release. Acid rain and carbon dioxide leads to chemical weathering of rocks.
Weathering is the physical disintegration and chemical decomposition of rocks to form sediments and soil.
- Mechanical weathering is also known as physical rock weathering.
- In this type of weathering huge masses of rocks are broken down into tiny pieces.
- When plant grows on rocks, their roots penetrates through cracks in the rock and can disintegrate it.
- Some animals burrow and bore deep into rocks.
- When a rock mass is lifted from the top of another, pressure release leads to the formation of exfoliation in which a rock resembles an onion peel.
