Answer:
Earthquake's magnitude is defined as the measure of the amplitude of the seismic waves. A seismometer or seismographs are used to measure seismic waves. So, the statement describes one aspect of an earthquake's magnitude is that Earthquake's magnitude depends on the size of seismic waves
Explanation:
Which statement describes one aspect of an earthquake's magnitude? It is based on the size of seismic waves.
Answer:
False
Explanation:
The primary productivity is higher than the secondary productivity, or any other productivity for that matter. The primary productivity comes from the producers, and it basically represents the total biomass of the producers. The producers outnumber and outweigh all other organisms by far, so they produce significantly much more biomass than any other type of organisms, thus being rated on the top for productivity.
Answer:
A. Lesser substance in a solution
Explanation:
Hope this helps! Have a nice day :)
Given that Landform F is a headland.
The effect of waves on the headland – Energy from waves will
be concentrated on the headland.
How the headland will change over time – The headland will
erode and level out with the rest of the shore.
Answer:
All spheres feel the effect of a volcanic eruption and earthquake
Explanation:
The spheres considered include the lithosphere, biosphere, atmosphere, hydrosphere and anthroposphere. Volcanic eruptions result from the movement of molten magma from below the earth crust either gently or in an explosive form while earthquakes are caused by the seismic movement of waves in the earth crust resulting in intense shaking. The lithosphere is where both the volcanic eruption and earthquake are triggered. This usually results in damage to the earth crust and damage the surface of the earth crust as well called the mantle. The biosphere made up of plant and animals is usually destroyed by both earthquakes and volcanic eruptions due to being swallowed up below the ground as well as the release of toxic gases from below that can affect their chances of survival. The atmosphere made up of the gases in and around the clouds and air we breathe become polluted, visibility becomes impaired and life unbearable as a result of volcanic eruptions and earthquakes. The hydrosphere made up of water body is seriously affected as pollutants such as toxic substances from the magma and even waste are brought to the surface to contaminate our source of livelihood and survival which is water. Pollutants in the air are also washed into water bodies when it rains. The anthroposphere made up of humans and their activities on the earth surface are severely impacted by volcanic eruption and earthquakes. Scenes of building collapse, molten magma killing humans and destroying buildings will be too much to bear. There will be no food as agriculture will be severely impacted hence making human survival nearly impossible.
