How can scientist locate the epicenter of an earthquake

Answers

Answer 1

Scientist use triangulation method to locate the epicentre of an earthquake from the data collected from Seismograph.  

Explanation:

The seismic data from three different location is collected to locate the intersect point as the epicentre point to be determined. Each earthquake is recorded in seismogram in different location.

A seismogram is the output from a graph called seismograph, which is used to determine the epicentre of an earthquake. There are two waves namely P-waves or Primary waves and S-waves or secondary waves that are considered while finding the epicentre of an earthquake.  

With the seismogram, P-waves appears first before S-waves, since they travel faster through three states of matter. Thus, data from seismograph is used for locating “epicentre of an earthquake”.

Answer 2

Answer:

-Record of waves from at least 3 seismograms are used to locate earthquakes.

-Difference inn arrival times of P and S waves give distance from seismometer to earthquake

Which information does a geographer avoid using when defining regions

Answers

When defining regions, geographers avoid using subjective information in determining boundaries. This includes opinions and perceptual information. So the answer is Subjective information.

Answer:

When defining regions, geographers avoid using subjective information.

Explanation:

When the information that is fed is based on personal points of view, personal opinions, irrelevant past experiences, unclear memories from the past, feelings, emotions, judgments, influenced thoughts, etc., it can be termed as subjective. This kind of information cannot be relied upon much because it is not based on solid facts and figures. If there are possibilities that the work being done would be looked at as a reference in the coming future, it is preferable to avoid relying on subjective information.

what is greenhouse gas

Answers

Greenhouse gas:

Greenhouse gas (GHG) are gases that trap heat in earth's atmosphere. They are named after greenhouse, a place with windows that allows sunlight to enter. This sunlight creates warmth and the greenhouse doesn't let the warmth escape. That's also the way greenhouse gases act.

They allow the sunlight to pass through the atmosphere and don't let that heat escape thus keeping the earth from getting too cold. Some of these gases are water vapours, carbon-di-oxide, ozone and methane. Greenhouse gases help in keeping the earth heat but due to human activities there has been an increase these gases in the atmosphere leading to global warming.

According to definitions, a greenhouse gas is a gas that produces the greenhouse effect by absorbing and emitting radiant energy at thermal infrared wavelengths.

The main greenhouse gases in the atmosphere of the Earth are ozone, carbon dioxide, methane, nitrous oxide, and water vapor.

The use of fossil fuels, the destruction of forests, and the raising of animals are all having a growing impact on the climate and the earth's temperature.

This amplifies the greenhouse effect and causes the atmosphere to contain significantly more greenhouse gases, which contributes to global warming.

Therefore, a gas that generates the greenhouse effect by absorbing and radiating energy at thermal infrared wavelengths is referred to as a greenhouse gas.

Match each question to the essential element it addresses.

Answers

The questions are based on geographic elements such as location, topography, climate, and culture, all of which pertain to 'the World in Spatial Terms'. These inquiries help in understanding spatial relationships and the interaction between people and the environment in Geography.

Understanding Geographic Questions

The series of questions presented here are designed to elicit information about the relative location, environmental characteristics, human geography, and spatial relationships for any given region.

Each question matches to the essential element of 'the World in Spatial Terms', as they all ask for information about the position and interconnections of different places.

Here is a breakdown of what each question addresses:

'Where is this happening?' and 'Where are the cities located?' address the absolute or relative location of an event or cities.

'Is the place by a river or on a mountain?' inquires about the topographic features and landscape positioning.

'How far are these places from each other?' relates to the spatial relationships and distance between location.

'Is the location warm or cold?' is oriented towards understanding the climatic conditions of the place.

'Which religion do the people practice?​' explores the cultural and religious aspects of the human environment in that location.

Asking such questions is fundamental in geography and when using Geographic Information Systems (GIS).

They help fill in the gaps in our mental maps, promoting a greater understanding of how we relate to different places around the world.

For example, comparisons of nearby ocean currents might demonstrate how certain places experience certain weather patterns, while inquiries about the presence of mountain ranges or rivers can reveal how natural features impact human settlement and activities.

Geographic questions are the building blocks that lead to a deeper understanding of the complex relationship between humans and the environment by situating places within their spatial context and providing insight into issues ranging from climate to cultural practices.

A is the answer, because the moon isnt as powerful as the earth. BUT still has a pull when you jump you end up back on the moon

Answer:

If Earth's gravity were much less powerful, our atmosphere would be similar to the moon's.

Explanation:

The gravity on the Moon is 16.66% of what is on Earth. This kind of gravity,  in astronomical language, is called 'microgravity'. Much less gravitational power on Earth would have turned it into microgravity, which would apparently have been unable to hold down most of the gases that constitute the atmosphere on Earth. For the gravity on the Moon is very less, it only has a few gases like sodium and potassium. Most of he gases that are present on the Moon are not naturally found on Earth.

write 125 as the product of three factors and as a power of base 5​

Answers

5x5x5 for the product of three factors and 5^3

Final answer:

The number 125 can be written as the product of three factors, 5 × 5 × 5, or as a power of base 5, which is 5³.

Explanation:

To write the number 125 as the product of three factors using a base of 5, we can express it as 5 × 5 × 5. This is because multiplying five by itself three times equals 125.

Additionally, to express 125 as a power of base 5, we use 5³, which represents five multiplied by itself three times. In mathematical terms, the exponent is '3' and the base is the number '5.' Therefore, 125 can be written as 5³, which equals 5 × 5 × 5, or 125. This is also referred to as cubing the number 5.

Why does Australia have a wide variety of unique wildlife species?​

Answers

Australia's vast land area and diverse ecosystems have allowed for the evolution of a wide variety of unique wildlife species, making it a global biodiversity hotspot. The correct answer is A. Because of its large land area and diverse ecosystems.

Australia's unique wildlife diversity is primarily attributed to:

a. Because of its large land area and diverse ecosystems.

Australia is characterized by its vast land area, making it the world's sixth-largest country. Its immense size offers diverse habitats, ranging from deserts to rainforests and everything in between.

This diversity of ecosystems has allowed for the evolution of a wide array of unique wildlife species.

Some key factors contributing to Australia's rich biodiversity include:

Isolation: Australia's geographic isolation for millions of years led to the evolution of species in relative isolation from other continents. This isolation allowed for the development of distinct and unique flora and fauna.

Varied Climates: The continent's diverse climate zones, from tropical in the north to temperate in the south, support a wide range of habitats and adaptations for different species.

Ancient Landscape: Australia's ancient landscape, including its unique geology and topography, has shaped its ecosystems and species over a long geological history.

Gondwana Heritage: Many of Australia's unique species have ancient roots in the supercontinent Gondwana, which once included what is now Australia, providing a legacy of ancient lineages.

While the other options (b, c, and d) can play roles in biodiversity and conservation, the primary reason for Australia's remarkable variety of wildlife species is its vast land area and the diverse ecosystems it encompasses.
