3ASTRONOMY1A. It basically refers to the apparent path of the sun around the sky. The term eclipticis used todescribe the circular path that the sun appears o follow within the course of the year. It is thecircular path on the celestial sphere. It is the basis of the ecliptic coordinate system. This is alsomarks the annual path of the sun. It is the projection of the orbit of the Earth onto the celestialsphere.B. The seasons are usually caused due to the tilt of the rotational axis of the earth. The axis tiltsaway or towards the sun as in the course of its yearlong travel around the sun (Krisha et al 2016).2B. A lunar eclipse is usually caused when the Moon enters the shadow of the earth. This doesnot happen every month or after every twenty eight days because the orbit of the Earth aroundthe sun is not the same plane in accordance to the orbit of the Moon around the Earth. Only at thetime when the Moon is crossing the plane of the orbit of the Earth, the lunar eclipse can occur.3A. As a general rule, metal have a higher density than rocks, so since the average density of allrocks is approximately 3000kg meter cube and that of the Earth is 5000 meter cube. Thisindicates a large metallic mass present inside the earth (Srivastava et al 2015). This metallicmass would also explain the cause the Earth’s magnetic field. Hence, from this it is apparent thatthe Earth contains a metallic B. It is because the temperature inside the earth increases at a rateof one degree centigrade for every 32m in depth. So, at the core which is the inner most layer ofthe earth, the temperature will be high enough to melt rocks. However, the core consists ofmolten material and is not exactly liquid in nature due to the tremendous pressure exerted by theoverlying layers.
