Altitude. 1. **Space extended upward; height; the perpendicular elevation of an object above its foundation, above the ground, or above a given level, or of one object above another**; as, the altitude of a mountain, or of a bird above the top of a tree. 2.

## What is the altitude in physics?

Altitude is **the elevation of an object from a known level or datum**.

## What is an example of altitude?

altitude noun [C] (HEIGHT)

height above sea level: The city of Denver is situated at an altitude of almost exactly one mile. Altitude is also the distance measured by an angle made by a point on the earth to a star and to the horizon (= place where earth and sky seem to meet).

## What is the definition of altitude for kids?

Altitude is **how high something is compared to the ground, or sea level**, and it’s important because of how it can affect people. Imagine the air around you and above you. The atmosphere (the air around the earth) pushes down on the earth.

**What is altitude in life science? – Related Questions**

## Does altitude mean height?

Although **the term altitude is commonly used to mean the height above sea level of a location**, in geography the term elevation is often preferred for this usage. Vertical distance measurements in the “down” direction are commonly referred to as depth.

## What is altitude class 5th?

Altitude means **height above the ground or above the sea level**. Common uses include aviation (flying, parachuting, gliding), and geography/surveying. In geometry it is also used as the height of the object itself. Generally, altitude is the distance one thing is above another thing.

## What are 3 facts about altitude?

Effects of high altitude on humans

**Altitudes above 1,500 metres (4,900 ft) start to affect humans**. Humans cannot live in very high altitudes above 5,500–6,000 metres (18,000–19,700 ft). Atmospheric pressure decreases at high altitudes. This affects humans because there is less oxygen to breathe.

## How do you measure altitude?

**Altimeters on the flight deck measure definitive altitude, and use a barometer to measure atmospheric pressure**. As most of us know, the higher you go, the lower the air pressure around you. This is why a pressure altimeter (really an aneroid barometer) is used to measure aviation altitude.

## What is meant by altitude of the sun?

The altitude angle (sometimes referred to as the “solar elevation angle”) **describes how high the sun appears in the sky**. The angle is measured between an imaginary line between the observer and the sun and the horizontal plane the observer is standing on.

## Why is it colder at altitude?

High-altitude locations are usually much colder than areas closer to sea level. This is due to the **low air pressure**. Air expands as it rises, and the fewer gas molecules—including nitrogen, oxygen, and carbon dioxide—have fewer chances to bump into each other. The human body reacts to high altitudes.

## What altitude is sea level?

It is **6,356.752 km (3,949.903 mi) at the poles** and 6,371.001 km (3,958.756 mi) on average.

## Is altitude an angle?

**The altitude angle (sometimes referred to as the “solar elevation angle”) describes how high the sun appears in the sky**. The angle is measured between an imaginary line between the observer and the sun and the horizontal plane the observer is standing on.

## Is altitude always 90 degree?

Yes, the altitude of a triangle is a perpendicular line segment drawn from a vertex of a triangle to the base or the side opposite to the vertex. Since it is perpendicular to the base of the triangle, **it always makes a 90° with the base of the triangle**.

## How many altitudes are there?

Answer: Three

An altitude of a triangle is a line segment that starts from the vertex and meets the opposite side at right angles. **A triangle has three altitudes**– one end is at the vertex and the other on the opposite side. An altitude is also known as the height of the triangle.

## What is altitude in a triangle?

The altitude of a triangle is **the perpendicular drawn from the vertex of the triangle to the opposite side**. Also, known as the height of the triangle, the altitude makes a right-angle triangle with the base.

## What is an altitude Class 7?

An altitude of a triangle is **the perpendicular line drawn from the vertex of the triangle to the opposite side**. The altitude of a triangle is also known as the height of the triangle.

## What are the properties of altitude?

Properties of Altitudes of a Triangle

The altitude is the shortest distance from the vertex to its opposite side. The 3 altitudes always meet at a single point, no matter what the shape of the triangle is. The point where the 3 altitudes meet is called the ortho-centre of the triangle.

## Does a triangle have 3 altitudes?

**In each triangle, there are three triangle altitudes, one from each vertex**. In an acute triangle, all altitudes lie within the triangle. In a right triangle, the altitude for two of the vertices are the sides of the triangle. In an obtuse triangle, the altitude from the largest angle is outside of the triangle.

## What is the longest altitude of a triangle?

Thus, the longest altitude is **perpendicular to the shortest side of the triangle**. The altitudes are also related to the sides of the triangle through the trigonometric functions.

## Are all altitudes of a triangle equal?

**If all the three altitudes of a triangle are equal, the triangles are equilateral.**
