why do you think mauna loa erupts periodically instead of steadily

Answers

The 1984 eruption of Mauna Loa volcano, Hawaii, produced about 220 million cubic meters of lava of remarkably homogeneous composition. No significant compositional changes occurred during the 22‐day eruption, and along the 20 km vent system, even though crystallinity increased substantially, accompanying a decline in the eruption rate. Such homogeneity in lava composition is typical of many historic Mauna Loa eruptions. The 1984 lava, along with most other homogeneous Mauna Loa lavas, is multiply saturated, crystallizing olivine, clinopyroxene, and plagioclase. Bulk compositions are “perched” at the intersection of an olivine‐control trend with a trend for more differentiated lavas. There is no evidence to indicate that the 1984 lava is a differentiate of the 1975 magma, or that it results from mixing a new batch of magma with differentiated melt remaining in the magmatic plumbing system after the 1975 eruption. It is proposed that these lavas are erupted directly from a small, continuously replenished magma reservoir located about 3–4 km beneath the summit caldera. Successive eruptions therefore provide a sampling of magma chamber processes, and small but discernible changes in lava composition reflect the competing processes of magma supply, differentiation, and eruption.

Calculate the speed of a wave with a wavelength of 6 meters and a frequency of 3 hertz.

You should be using the formula
speed = wavelength x frequency

Answers


The answer is 18 you multiply wavelength (6) times frequency (3)
Painted 18 because the wave length is 6 m and the frequency is 3.So 6×3 = 18

What is the relationship between guard cells and stomata in plants?

Guard cells open and close the stomata to regulate the rate of transpiration. Hope I helped

Are there any steps of the rock cycle that do NOT connect directly to one another? Explain why this may be the case using at least two examples.

please helpp

Answers

Answer:

rocks are destroyed

explanation

ricks are never destroyed they descompose

There are no steps in the rock cycle that do not connect directly to one another. The rock cycle describes the continuous process by which rocks are formed, weathered, eroded, transported, deposited, and lithified, leading to the formation of new rocks.

What are the steps in rock cycle ?

Each step of the rock cycle is interconnected and depends on the other steps. For example, the formation of sedimentary rocks requires the weathering and erosion of preexisting rocks, the transportation and deposition of the resulting sediments, and the lithification of the sediments into rock.

Without the weathering and erosion of preexisting rocks, there would be no sediment to form sedimentary rocks.

Similarly, the formation of metamorphic rocks requires the heat and pressure of burial and tectonic activity, which in turn is influenced by the existing rock formations and geological processes of the area.

Another example is the formation of igneous rocks, which can occur through the melting and solidification of preexisting rocks, or through volcanic activity.

Answer:

I, II

Explanation:

The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.

lack of soil and shade

lack of food and nutrients

Answers

lack of water and sunlight

Water and sunlight are necessary for photosynthesis to occur absence of these turned the grass brown.

What is photosynthesis?

It is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy  through the process of cellular respiration.

Some of the energy which is converted  is stored in molecules of carbohydrates like sugar and starches  which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis  are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the content of oxygen in earth's atmosphere.

The process begins with proteins absorbing light energy  which are called reaction centers and contain a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles called chloroplasts while in bacteria they are present in plasma membrane.
