The moon is a major influence on the Earth’s tides, but the sun also generates considerable tidal forces. Solar tides are about half as large as lunar tides and are expressed as a variation of lunar tidal patterns, not as a separate set of tides. When the sun, moon, and Earth are in alignment (at the time of the new or full moon), the solar tide has an additive effect on the lunar tide, creating extra-high high tides, and very low, low tides—both commonly called spring tides. One week later, when the sun and moon are at right angles to each other, the solar tide partially cancels out the lunar tide and produces moderate tides known as neap tides. During each lunar month, two sets of spring tides and two sets of neap tides occur (Sumich, J.L., 1996).
People first tamed animals a very long time ago. It was a necessity - they needed to have meat, milk, fur at hand. It was easier to have animals near than to go hunting in dangerous conditions. Then people tamed the next group of animals - to protect the useful animals from the wild. And suddenly humans realized that it was fun to have a home animal. Thus first pets took their place in the homes of our ancestors. Nowadays people can choose a wide range of different pets - cats, dogs, mice, hamsters, snakes, lizards, birds. The most popular are cats and dogs. But I think it is easier to have a caged pet. For example, chinchillas. Because modern people spend most of the time at work, in my opinion it is cruel towards dogs or cats who might feel lonely. But if I speak of myself I would choose a dog, because it is a loyal and kind creation and I like long walks where my dog would be a companion.
