Weather Instruments
Which weather instrument measures air pressure?
A barometer.
What do the lines on a weather map called isobars represent?
Isobars represent areas of equal air pressure. The closer the lines are to each other, the stronger the winds are.
Why are camels well-suited to living in hot desert climates?
Camels are well-suited because they can store water in their humps, have long legs to keep their bodies away from the hot ground, and their thick fur protects them from the sun.
What is population density?
Population density refers to the number of people living per unit area, typically per square kilometre.
What is the epicenter of an earthquake?
The epicenter is the point on the Earth's surface directly above where the earthquake originates (the focus). It is usually the area most affected by the earthquake.
What does a wind vane show?
The direction the wind is coming from.
What does a cold front on a weather map look like?
A cold front is usually shown as a blue line with triangles pointing in the direction the front is moving. It often brings cooler, wetter weather.
What is the temperature like in the desert at night?
At night, desert temperatures can drop dramatically, sometimes as low as 5°C (41°F) or even freezing, because the lack of cloud cover allows heat to escape quickly.
What is migration?
Migration is the movement of people from one place to another, either within a country (internal migration) or across borders (international migration), often in search of better living conditions or jobs.
What is the focus of an earthquake?
the focus (or hypocenter) is the point inside the Earth where the earthquake starts. It is usually located along a fault line, deep beneath the surface, and is the source of seismic waves.
What does an anemometer measure
It measures wind speed
What does a warm front on a weather map look like?
A warm front is shown as a red line with semi-circles, indicating warmer air pushing into a cooler area. It can bring light rain or cloudiness.
What is the main function of the spines on a cactus?
the spines on a cactus help reduce water loss by minimizing airflow around the plant and protect it from animals that might want to eat it.
What are push factors in migration?
Push factors are conditions that drive people to leave their home country or region, such as poverty, lack of jobs, war, or natural disasters.
What is a fault line?
A fault line is a crack or fracture in the Earth's surface where two tectonic plates meet. Movement along these fault lines causes earthquakes.
What is the Campbell-Stokes recorder used for?
To measure the duration of sunshine during the day.
What type of weather is usually associated with low-pressure areas on a weather map?
Low-pressure areas are typically associated with cloudy, rainy, and stormy weather, as air rises and cools, causing condensation.
Why do cacti have thick, fleshy stems?
The thick, fleshy stems of a cactus store water, allowing the plant to survive in dry conditions where water is scarce.
What are pull factors in migration?
Pull factors are conditions that attract people to move to a new area, such as better job opportunities, safer environments, better education, and improved quality of life.
What features do earthquake-proof buildings have to help them withstand an earthquake?
Earthquake-proof buildings have flexible foundations, shock absorbers, reinforced steel structures, and damping systems that allow the building to move slightly with seismic waves, reducing the risk of collapse.
Where should a hygrometer be placed for accurate readings, and why?
Inside a Stevenson screen, to ensure it is sheltered from direct sunlight and weather conditions.
How can you identify a high-pressure area on a weather map?
A high-pressure area is usually shown with an "H" and is associated with clear skies and dry weather, as air sinks and warms, preventing cloud formation.
Why do some cacti have deep roots while others have shallow roots?
Some cacti have deep roots to access water from deeper underground sources, while others have shallow roots that can quickly absorb water from rainfall or dew that is close to the surface.
what is birth rate
Number of babies born per 1000
what do rollers in a building do
help the building sway from side to side
