<h2>Answer: Eccentricity
</h2>
The orbit of a body around another in space, as is the case of the Earth orbiting the Sun, is described by six orbital elements that determine its orientation, position, size and shape.
In the specific case of the shape of the orbit, this is determined by its <u>eccentricity</u>, which <u>varies between 0 and 1.
</u>
When the eccentricity is 0, the shape of the orbit is circular, when this value begins to vary until approaching 1 (without reaching 1), the shape of the orbit becomes more elliptical.
In this sense, the eccentricity of the orbit of the Earth around the Sun is 0.2, which means is <u>nearly circular</u>. However, due to orbital perturbations this value may change over time.
Horrible situations we have in the world is, racism still, inequality, homeless people, homeless animals, mental illnesses- depression, anxiety, have increased in this era. As for Mexico, Mexico is also located at a high altitude, the sunlight is stronger than that on the sea level, causing pollutants to react with each other producing a toxic gas called ozone.
Mass: mass is the amount of material in an object. Mass is measured with a balance, usually in grams or kilograms
Volume: volume is the amount of space occupied by an object. Volume is measured using a graduated cylinder or is determined by calculation using the dimensions of the object. Volume is measured in cm3, m3, mL and L.
Density: Density is a mass to volume ratio. Density can be used to identify a substance because every pure substance has a unique density value. Objects with smaller densities will float in liquids that have greater densities.
