What are the four main factors that affect aquatic ecosystems?
The four main factors that affect aquatic ecosystems are waters depth, temperature, flow, and amount of dissolved nutrients.
What are the two main factors that affect the amount of erosion?
Rock type Elevation Precipitation
What are two main factors that affect where groundwater becomes surface water?
The height of the water table and the height of the ground surface. Got it from past TAKS tests.
What are the three main factors that govern aquatic ecosystems?
Factors that affect biodiversity in an ecosystem inculde area,climate,diversity of niches,and keystone species.
Which two factors affect the temperature that rocks melt at?
The two main factors that affect the temperature at which rocks melt are the composition of the rock and the pressure acting on it. Different minerals have different melting points, so the composition of the rock will determine its melting temperature. Additionally, pressure can increase or decrease the melting temperature of rocks, with higher pressure generally increasing melting temperature and lower pressure decreasing it.
What factors affect magma's viscosity?
The two main factors that affect viscosity are temperature and silica content. Higher temperatures lower viscosity while higher silica content increases viscosity.
Why do volcanic eruptions differ?
The main cause of differences in volcanic eruption characteristics is due to the viscosity of the magma. High viscosity magmas are high in sticky silica which traps gas and produces explosive eruptions. Low viscosity magmas are low in silica and produce eruptions with far less energetic characteristics.
What 3 factors determine magma viscosity?
The three elements that determine viscosity in magma are:TemperatureSilicaOxides (gases)Viscosity changes the way in which magma will flow. Magma with low viscosity will flow much more easily than high viscosity magma.
What are the main factors that contribute to total peripheral resistance?
Blood vessel diameter,blood viscosity and total vessel length
What are four main factors that affect aquatic ecosystems?
The four main factors that affect aquatic ecosystems are waters depth, temperature, flow, and amount of dissolved nutrients.
What factors affects salinity?
There are several factors that affect salinity. Some of the main factors include evaporation and precipitation which will affect the salinity of oceans and seas.
What are factors that affect literacy rates?
poverty is the main factor that affect literacy rates
Name the factors that may affect osmosis?
There are at least 2 main factors that may affect osmosis. These 2 factors are amount of water and membrane permeability.
What is the main idea of factors affect climate?
greenhouse effect
What causes volcanoes to erupt violently while others simply leak molten rock?
There are two main factors factors: gas content and magma viscosity. All magma has some amount of gas dissolved in it. This gas is released when the magma is exposed to lower pressure near the surface. In magma with a high gas content the gas bubbles out of solution and expands explosively in the presence of low pressure. If the gas content is low it may only result in a bit of bubbling. Viscosity is the tendency of a liquid to resist flowing. For example, maple syrup is more viscous than water. Magma varies in viscosity depnding on its temperature and composition. Lower temperatures and higher silica content make a more viscous magma. More viscous magmas usually have a higher gas concentration. Additionally, in viscous magmas, the gas is less likely to escape ahead of the magma in the prelude to an eruption.
What are the main abiotic factors that affect yellow stone national park?
The main abiotic factors that affect yellow stone national park would be hot springs, water, soil, climate and rock. These all interact with biotic factors.
What factors affect the sales?
consumer behavior is influenced. Placement and media channel are two main factors that will affect advertising in effectiveness and perception of brand.
