How Do Agates Form? | Penn State University

It's like asking, How do you stop an agate: For the secret to making an agate, Heaney believes, is how silica (silicon dioxide, or SiO 2) dissolves in water. An agate starts with a cavity, a void in the rock. The best are found in basalt, a young volcanic rock.

Basics of Plant Respiration | PRO-MIX

 · Basics of Plant Respiration. Tuesday, Septem | Jose Chen Lopez The process of respiration in plants involves using the sugars produced during photosynthesis plus oxygen to produce energy for plant growth. In many ways, respiration is the opposite of photosynthesis. In the natural environment, plants produce their own food to survive.

Weathering and Erosion in Desert Environments - USGS

However, it is somewhat paradoxical that the mechanical breakdown of rock proceeds relatively quickly in the arid climate. In wet regions, the ground remains partially or fully saturated. Plants typically cover the landscape and bind the soil, and hence, prevent erosion.

Why Does Basalt Weather Faster Than Granite? | Hunker

Weathering, how rocks break down, can happen in a multitude of ways, including adding water and freezing, impacting plant roots, impact from another object and when minerals expand. Basalt weathers faster than granite because it is not as hard and it's easier for outside substances to impact and manipulate its structure.

Types of Volcanoes - Oregon State University

Types of Volcanoes . Many people are interested in ways to classify volcanoes. There is probably a natural human instinct to try and give labels to all things. This is not a bad instinct and many times it makes it easier to understand the particular thing that is being classified.

Plateau - The shape of the land, Forces and changes ...

The lava that floods the landscape to create a lava plateau is composed primarily of basalt, a hard, often glassy, black volcanic rock. Basalt has low silica content, and the lava it creates has a high temperature. These two properties combine to produce lava that flows quite rapidly.

Basalt - Wikipedia

Basalt (US: / b ə ˈ s ɔː l t, ˈ b eɪ s ɒ l t /, UK: / ˈ b æ s ɔː l t, ˈ b æ s əl t /) is a mafic extrusive igneous rock formed from the rapid cooling of magnesium-rich and iron-rich lava exposed at or very near the surface of a terrestrial planet or a moon. More than 90% of all volcanic rock on Earth is basalt. Basalt lava has a low viscosity, due to its low silica content ...

Coal: Anthracite, Bituminous, Coke, Pictures, Formation, Uses

It can only occur under one of two conditions: 1) a rising water level that perfectly keeps pace with the rate of plant debris accumulation; or, 2) a subsiding landscape that perfectly keeps pace with the rate of plant debris accumulation. Most coal seams are thought to have formed under condition #2 in …

Dryland salinity – causes and impacts

(e.g. plants, animals, aquatic ecosystems, water supplies, agriculture and infrastructure). Dryland salinity occurs in unirrigated landscapes (Figure 1). Primary and secondary salinity . Primary (or inherent) salinity is the natural occurrence of salts in the landscape for example salt marshes, salt lakes, tidal swamps or natural salt scalds.

Basalt and Granite

The trick is to heat the basalt back up again so it can melt and give the iron another shot at the core. It wants to be there, and heat is the key which unlocks the door. As it turns out, most of the ocean floor is basalt, and most of the continents are granite. Basaltic crust is dark and thin and heavy, while granite is light and accumulates ...

Photosynthesis Quiz - Do You Know How Plants Make Food?

Photosynthesis occurs in the green tissue of plants. This is primarily in the leaves, although photosynthesis also occurs in stems. Roots aren't exposed to light, so there's no point for a plant to put chlorophyll in them. Flowers serve a reproductive purpose, so again, there's no reason for plants to use them for photosynthesis.
