It varies from place to place, in response to the five factors that form it: climate, topography, organisms, the parent rock below surface, and time. Our Maine soils developed since the last glacier moved across the region, largely in response to the parent rock (largely granite) and topography. Most Maine soils are acidic, and have a somewhat depressed ability to hold and exchange nutrients used by plants. Our native plants ev

  • 4 Types and Examples of Chemical Weathering

    Oct 29, 2019· Lichens can have a profound effect on rock. Lichens, a combination of algae and fungi, produce a weak acid that can dissolve rock. Plant roots are also an important source of chemical weathering. As roots expand into rock, acids can change the minerals in the rock. Plant roots also use carbon dioxide, thus changing the chemistry of the soil.

  • The Effect of Green Light on Plants Hunker

    Chlorophyll in the plant is the pigment that absorbs light. Light is made up of three different colors: red, blue and green. The reason that green plants appear that color is that they reflect that color in the light spectrum. In other words, the chlorophyll in the plant absorbs the red and blue light much more readily than the green light.

  • How Does Carbon Dioxide Affect Plant Growth?

    Apr 13, 2020· Growth of plants depends on more than just carbon dioxide. The plants need minerals and water to sustain the growth process. An increase in carbon dioxide concentrations in the air does not necessarily mean these other requirements are available. Thus, while increasing carbon dioxide encourages greater growth, it does not guarantee it.
