OverLord2011 [107]3 years ago
8 0
One of the reasons why Plinian eruptions are more violent is that they release more viscous magma than Hawaiian hawaiian eruption. the thicker the magma the more violently it is released on the ground surface. Hawaiian eruption on  the other hand release thin magma that flows peacefully but fast. the other reason hawaiian eruptions are less violent is the presence of many side fissures where some magma escapes through in addition to the main vent. these fissures help to reduce pressure and therefore magma flows peacefully. in plinian eruptions magma is mainly released from the main vent.

Refer the the graph below showing the absorption spectrum of chlorophyll a. Explain what the graph is showing
Stella [2.4K]

Answer: The graph shows that chlorophyll a absorbs light principally around 420-450 nm and 650-680nm wavelengths

Explanation: Chlorophyll a is a pigment found in plants that traps light energy for use in photosynthesis. Chlorophyll a absorbs light mostly in the blue and orange-red wavelengths. This is shown in the graph, where the peaks are around the 400nm and 600nm wavelengths, corresponding to blue and red in visible light.

This absorption means the pigment is 'excited' by this light, sending into a higher state if energy which provides energy for the reactions of photosynthesis.

How do accessory pigments help chlorophyll?
erastova [34]
The compounds present in plants that, in a way, assist in the absorption of light during the process of photosynthesis, are accessory pigments. As their name suggests, they act as helpers or assist chlorophyll in absorption of light. These may be chlorophyll variants or other classes.
