Seismographs are unable to pick up seismic waves in which area of earth?.

Answers

Answer 1

Answer:

The area is called "The Shadow Zone".

Answer 2

Seismographs are unable to pick up seismic waves in the Earth's outer core because the molten state of this layer inhibits the transmission of seismic waves in a way that can be recorded by seismographs.

Seismographs are instruments used to detect and record seismic waves, which are vibrations that travel through the Earth's interior during an earthquake. They consist of a sensor, called a seismometer, that records the ground motion caused by these waves.

The Earth's core is divided into two parts: the outer core and the inner core. The outer core is a layer of molten iron and nickel that surrounds the solid inner core. It is located between the Earth's mantle and the inner core. Seismographs are unable to pick up seismic waves in the Earth's outer core due to the nature of the material it consists of. The molten state of the outer core prevents the transmission of seismic waves in a way that can be detected by seismographs.

Sixty-five percent of global greenhouse gas emissions are made up of carbon dioxide, while only sixteen percent are made up of methane gas. Which of the following best explains why scientists are increasingly concerned about the effect of methane gas emissions on global climate if they are a relatively small percent of greenhouse gases released?.

Answers

The statement that best explains why scientists are increasingly concerned about the effect of methane gas emissions on global climate is that the Methane gas has a higher global warming potential (GWP) than carbon dioxide does, so it can trap more heat in the atmosphere.

What is Global warming?

Global warming is also called climatic change because of the existence of heating of Earth's climate system which are primarily due to human activities.

Hence, the scientist are more concern because Methane gas has a higher global warming potential (GWP) than carbon dioxide does, so it can trap more heat in the atmosphere.

Explain how the risk of tectonic hazards can be reduced (4 marks - include 4 ways)

Answers

To reduce vulnerability, organisations such as the United States Geological Survey (USGS), governments and charities need to do the following.

Reduce the impact of hazard

Monitoring tectonic activity using equipment may help predict and identify major events. In addition to this, setting up evacuation zones and hazard mapping are helpful techniques to reduce the impact of a hazard.

Build capacity to cope with the hazard

Educating people about what to do, and having regular earthquake drills, are helpful in building capacity to cope. In addition, having well equipped emergency service teams who are well trained also increases a country’s ability to cope. Buildings can also be designed in a way to better survive earthquakes. From skyscrapers in San Francisco, USA, to new community centres in Kali Jawi, Indonesia, buildings can be made earthquake proof.

Tackle the root cause of the vulnerability

Governments and organisations can help reduce the vulnerability by actively trying to reduce inequality and poverty in countries. Everyone, regardless of wealth, should have the same status and right to protection.

ET

Answers

Answer:

OD

Explanation:

YES, THE LINES L AND LY ARE PERPENDICULAR SLOPES DOES NOT EQUAL

Yes, line L1 and L2 are parallel because they have the same slope. Correct option is B.

To calculate the slope of the line passing through the points (0, 2) and (8, 4), you can use the formula for the slope of a line:

Slope (m) = (y2 - y1) / (x2 - x1)

Given the points:

Point 1: (x1, y1) = (0, 2)

Point 2: (x2, y2) = (8, 4)

Substitute the coordinates into the formula:

Slope (m) = (4 - 2) / (8 - 0)

Slope (m) = 2 / 8

Slope (m) = 0.25

The slope of the line passing through the points (0, 2) and (8, 4) is 0.25.

To calculate the slope of the line passing through the points (-8, -6) and (0, -4), you can use the formula for the slope of a line:

Slope (m) = (y2 - y1) / (x2 - x1)

Given the points:

Point 1: (x1, y1) = (-8, -6)

Point 2: (x2, y2) = (0, -4)

Substitute the coordinates into the formula:

Slope (m) = (-4 - (-6)) / (0 - (-8))

Slope (m) = (-4 + 6) / 8

Slope (m) = 2 / 8

Slope (m) = 0.25

The slope of the line passing through the points (-8, -6) and (0, -4) is 0.25.

Wildfires can occur anywhere but are common in the forested areas of the United States and Canada. They are also susceptible in many places around the world, including much of the vegetated areas of Australia as well as in the Western Cape of South Africa. The climates are sufficiently moist to allow the growth of trees, but feature extended dry, hot periods. Fires are particularly prevalent in the summer and fall, and during droughts when fallen branches, leaves, and other material can dry out and become highly flammable. Wildfires are also common in grasslands and scrublands.
