The obliquity (axial tilt), precession (wobble), and the eccentricity (how close to being circular) of the Earth’s orbit, comprise the Milankovitch cycle. These three factors affect the amount of heat energy from the sun (solar heat) directed to Earth, influencing climactic changes and patterns.
The tilt of the axis mainly affects the amount of solar heat each hemisphere receives. The greater the tilt, the more solar energy is directed at the northern hemisphere. Along with precession, they also affect the length of days and nights experienced by certain parts of the Earth.
The eccentricity of the orbit affects the distance of the Earth to the Sun during its revolution in orbit. The orbit is an elliptical path followed by the Earth, with the Sun not exactly at the center. Thus, there is a time when the Earth is closest to the Sun (perihelion) and this allows the Earth to experience radiation the most. On the other hand, there is also a time when Earth is farthest to the Sun (aphelion). This difference in distance creates a heat exposure retained by the Earth. From the time of perihelion it absorbs so much solar energy and is gradually expended revolving but at the same time still absorbing solar heat – hotter global temperature
.
If the orbit was more circular, the distance of the Earth to the Sun will always be the same at any point in the orbit. Thus, allowing equal exposure to the Earth at all times. There will be no point in time in which the Earth will absorb so much heat. This will cause a cooler global temperature compared to the elliptical orbit.
Photosynthesis takes place in the roots of the plant
The whole human body is a lever system, that's how muscle work. Your joins are the fulcrum, your muscle contracts and hence is the effort. On the other side, whatever you're holding and the weight of your hand is the load. There are all 3 classes of lever system in your body.
Answer:
A person who fakes symptoms for a goal is called a malingerer, while a person who fakes a disease for no clear goal has a factitous disorder:
Explanation:
Malingerer is someone who attempts to shirk or escape from duty/ responsibility by feigning. Malingering is the result of a person desire to gain a reward or avoid something and it is not caused by any physical factors. While Factitious disorder entails a person acting as if he or she has a physical or mental illness.
