Based on evidence, scientists believe Earth is over four billion years old. Indirect evidence, such as radioactivity of certain elements found in rocks, as well as direct evidence, such as observations of Earth's rock layers, are used to help scientists make these calculations. Rock formations and the fossils within them can help scientists establish relative ages of major events in Earth's history. Which statement describes the most accurate conclusion scientists can make based on the evidence given? A) Scientists conclude sandstones with ripple marks might indicate a shoreline habitat or a riverbed. B) Upon discovering pieces of cracked limestone, a scientist concludes an earthquake happened in that area. C) After discovering a thick layer of igneous rock, scientists conclude that area was once part of an ocean. D) A scientist discovers a layer of dark metamorphic rock and concludes a volcano had erupted in that location.

relationships aren't everything. people everyday spend there entire life depending on reltionships and for someone to be there for them when this is absurd. why must people depend on someone else to bring them happiness? i'm not saying it wrong to feel happy with someone, but people feel that they need to be in a relationship in order to feel happy, when, this is not true. you can paint, write, read ir slend tume with family ir even spend time working in yourself. this can be an exciting experience to find yourself. it's bot wrong to be in a relationship but if you let it be your only source of happiness, than you will never find true happiness.

so, relationships are not always worth it. if you are so dependent on them, than in the end they arent worth it because you will realize how unhappy you really were. some people even tend to cut ties with family because they think they cabt make them happy, obly realtionships with a lover can. false. in order to find true happiness, one must learn to love themselves if they want to love someone else. it's unhealthy to be always depend on relationships and to alqays be in and out of one.

so live life, get that job you always wanted, buy those new shoes and love yourself. depend on yourself, not others. they arent worth it, you can make yourself more happier than most people can do to you. it's not woth it. take your time and have fun.
