In what way are volcanic eruptions and meteoric impacts similar?
A.Both can cause global cooling.
B.Both can cause global warming.
C.Both emit oxygen gas into the atmosphere.
D.Both have a greater effect on weather than on climate.
Answer:
A.Both can cause global cooling.
Explanation:
According to researchers, the impact of an asteroid and volcanic eruptions probably covered the planet with harmful dust and gases, which could change the climate and caused the early extinction of many species.
Life on earth would take thousands of years to recover from the devastation.
"The scenario we suggested, that the impact of the asteroid would cause volcanism, reconciles with the facts we once thought was an unbelievable coincidence," said Mark Richards of the University of California at Berkeley.

why is russia officially call the russian federation
Answer:
Russia is officially called the Russian Federation (RF) because it is constituted of about 85 federal constituent units.
Explanation:
A federation is basically a larger government made up of many other smaller governing units of principalities. The country of Russia is divided into '85 such federal units' which are administered by their own local governing bodies. These local governing bodies are accountable to the central government of Russia. The central government performs supervision over the smaller federal units and is the supreme parent authority.The subfield of geography and geology concerned with the study of the origins, evolutions, form, and spatial distribution of the earth's landforms is
Weather-station measurements indicate that the dewpoint temperature and air temperature are getting farther apart and that air pressure is rising.which type of weather is most likely arriving at the station?
The weather station measurements indicating that the dewpoint temperature and air temperature are getting farther apart, combined with the rising air pressure, suggest that clear and more settled weather is likely arriving at the station.
The dewpoint temperature is the temperature at which air becomes saturated with moisture and dew can form. When the dewpoint and air temperatures are close together, it implies higher relative humidity, often associated with cloudier skies and potential precipitation. Conversely, when the dewpoint and air temperatures are farther apart, it usually signifies lower humidity and clearer skies. Rising air pressure typically indicates the approach of a high-pressure system, which is commonly linked to fair weather conditions. This transition can lead to sunny skies and less precipitation. Weather forecasting involves complex variables, but these signs—increasing gap between dewpoint and air temperatures alongside rising pressure—are classical indicators of improving weather conditions.
Secondary seismic waves (s waves) ______. are the slowest seismic waves travel through solids, liquids, and gases
Secondary seismic waves or s waves are the slowest seismic waves that travel through solids, liquids and gasses.
What are seismic waves?A seismic wave is a wave of acoustic energy that travels through the Earth. It can result from an earthquake, volcanic eruption, magma movement, a large landslide, and a large man-made explosion that produces low-frequency acoustic energy.
Seismic waves are studied by seismologists, who record the waves using seismometers, hydrophones or accelerometers. Seismic waves are distinguished from seismic noise which is persistent low-amplitude vibration arising from a variety of natural and anthropogenic sources.
The propagation velocity of a seismic wave depends on the density and elasticity of the medium as well as the type of wave. Velocity tends to increase with depth through Earth's crust and mantle but drops sharply going from the mantle to Earth's outer core.
Earthquakes create distinct types of waves with different velocities. When recorded by a seismic observatory, their different travel times help scientists locate the quake's hypocenter. In geophysics, the refraction or reflection of seismic waves is used for research into Earth's internal structure.
Scientists sometimes generate and measure vibrations to investigate shallow, subsurface structures.

what kind of fossil aging is used when scientists use the law of superposition?
Answer:
When scientists use the law of superposition, the type of fossil aging they use is known as relative aging.
Explanation:
Scientists use different methods of aging to determine the 'age of rock fossils'. One of these techniques is that of relative aging. In this technique, the scientists 'determine the age of the bottom-most rock fossil' first and go by the principle that every new layer of rock superpositioned above the lower rock is comparatively younger than the lower rock.Describe the disaster at Chernobyl.

The length of time that a volcanic eruption impacts the climate is largely determined by
Answer:
The length of time that a volcanic eruption impacts the climate is largely determined by whether the ash or gas reaches the stratosphere
Explanation:
A volcanic eruption releases gases and other particles in the atmosphere. The factor whether these released material reaches the stratosphere or not, determines whether that particular volcanic eruption will affect the climate or not.
The enormous output from the eruption gets released in the atmosphere. This output forms a permanent layer in the atmosphere over time and becomes a barrier to the sunlight reaching the earth.
The decrease in sunlight causes cooling effect thereby decreasing the temperature of the planet.
The time taken by the emission to reach the stratosphere determines the time taken by the emission to change the climate of the planet.

True Or False?
Answer:
The statement that states that the axis is the imaginary line which runs through the 'center of the earth' between the South and North Poles is true.
Explanation:
The Earth rotates on its geographic axis which is inclined at an angle of 23.5° with respect to the horizontal plane of the Earth's rotation. This axis passes through the geographic poles of and makes a straight line connecting the two poles located on two different hemispheres of the planet.Which earthquake severity scale varies from locality to locality for a single earthquake?

On a geologic map, strike represents the directional orientation of a fault.
Strike is a way of representing the 3D orientation of a planar surface on a 2D map. Fault can be characterized by brittle deformation in rocks. These faults can be oriented at any direction (Strike). Shear stresses can produce faults where movement can occur in strike direction.
Answer:
The statement that says 'on a geologic map, strike represents the directional orientation of a fault' is false.
Explanation:
If it is considered that the given geologic map is of a horizontal plane, then the 'direction of the rock' present on this horizontal plane would be represented by a strike on the given geologic map. To represent a fault on the 'geologic map', the symbol of a thick line inclined towards the right is used.How far do you have to go for the North Star not to be north anymore?

The gas that is the largest component of the atmosphere is _____.
a. water vapor
b. oxygen
c. carbon dioxide
d. nitrogen
e. argon
The gas that is the largest component of the atmosphere is oxygen. The correct option is B. In nature, nitrogen (N2), which accounts for about 78% of air, is the most prevalent gas. The second most prevalent gas after nitrogen (N2) is oxygen (O2).
Which gases are most important?One of the most crucial gases to humans is oxygen. Due to the necessity of carbon dioxide for photosynthesis in plants, it is one of the most vital gases for all life on Earth.
The other main factor is that, in contrast to oxygen, nitrogen is much more stable in the atmosphere and plays a much smaller role in chemical reactions that take place there. As a result, it has accumulated in the atmosphere to a much greater extent than oxygen over geological time.
Thus, the ideal selection is option B.
