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.
