Q. What are the 5 characteristics of minerals?
A. 1. Minerals are Natural. You just find them in nature 2. Minerals are inorganic. They don’t belong to any class of organic compounds. 3. Minerals are solids. They cannot he liquid or gas. 4. Definite Chemical Composition. A combination of a special minerals atoms are unique. They can’t be found in any other mineral. 5. Crystalline structure. Minerals have repeated arrangements of atoms or ions. Q. What are 5 physical properties that can used to identify a mineral? A. Colour, Hardness, Magnetism, Density, lustre Q. What is the difference between a mineral and a rock? A. Rocks can have organic remains and are usually a mixture of one or more minerals. Minerals are naturally recurring and inorganic solid. Q. Identify 2 active mines in B.C and what they mine. A. 1. Haddington Island Quarry. They produce andesite from the volcanic rock on the island. 2. New Afton Mine. They produce both gold and copper. Q. Why do you think it’s important to learn about minerals? A. It’s important to learn what things are made of and how it possibly creates an impact. It makes you think about should I use this product or not. Also to learn about where you live and what your province or state is in rich in.

Q: Do humans have the right to take resources from other parts of the solar system?
A: I believe we do have the right to take resources from other parts of the solar system. As the population grows and the demand for various things increases we do need start looking other ways to get resources. If we do this countries must work together to gain these resources to prevant fighting over them and to make sure everyone gets what they need. Q: Why is it important to study the Sun and other stars?
A: Our Sun is the closest star to us which makes it a lot easier to study stars. With having our own star we can understand what go’s on with our sun and other stars like it. Q: What is the Doppler effect and how does it tell us information about stars? What does it mean to be blue shifted or red shifted? A: It is the change in frequency and wavelength of a wave. This is caused by the change of distance between the object making the wave and whoever is seeing or hearing it. How they use the doppler effect on stars is to determine the velocity of them. When visible light is shifted to higher frequencies it is blue shifted and when light is shifted to lower frequencies it is red shifted. They use blue and red shifts to determine how far away an object is. When an object is moving towards us it is blue shifted but when the object is moving away it is red shifted. Q: Explain how the Hertzsprung-Russell diagram is created and what it represents. A: It is a graph that helps you measure the temperature and brightness of stars. Q: Over time, what will happen to our Sun? A: Our Sun will go through different stages of it’s life cycle until it dies. First it will turn into a red giant and engulf Mercury, Venus and Earth. Second, it will become a planetary nebula but not too long after that it will start to disperse and fade away. Last but not least it will shrink down and become a white dwarf slightly larger than the Earth. I used these sites to help me: Blue and Red Shifted Properties of Stars The Doppler effect Star Life cycle Q: What is a tide? What causes it?
A: A tide is the ocean rising and falling due to the gravitational forces of the moon and rotation of the Earth. Q: Is the moon moving away from the Earth? Explain. A: Yes the moon is moving away from the Earth. This is happening because of the gravitational forces of the moon and Earth. These forces cause a tidal bulge in the oceans. rotation of the Eath Q: What is different about the two crescent phases of the moon? A: Crescent phases of the moon are different becasue one of the phases is waning and the other is waxing. Q: Explain how solar and lunar eclipses occur? How are they different? A: A lunar eclipse is when the Earth’s shadow covers the moon or a small part of it. This happens when the Earth comes between the sun and the moon. A solar eclipse is when the moon blocks out of the sun for a short amount of time. This happens due to the moon coming between the sun and Earth. They are different because a solar ecpipse can be a total, partial or annular and alunar ecplipse doesn’t Q: Why don’t solar and lunar ecplises occur every month? A: It doesn’t happen every month because the Earth’s orbit around the sun is different from the moons orbit around Earth’s. Q: Why wasn't the zodiac symbol of your horoscope in the night sky at the time of your birth? What is this effect called?
A: It's different due to the wobble of the Earth. This wobble is called precession and has a 25,800 year cycle which causes the celestial equator and ecliptic to move which changes things around. Q: What causes the seasons? A: Earth's tilt is the reason we have seasons. It all depends of how much sun is hitting Earth as we revolve around it. We have summer when the Earth is tilted towards the sun and winter is caused by the Earth tilting away from the sun. Q: Why should we look out at the sky at night? What benefit does it serve? A: To learn more about the night sky and it's also pretty cool. Seeing the moon is pretty especially when you take a closer look at it. Too find all the constellations and think about if those suns have burned out. When lay down at night and look at the stars it can be very peaceful. Q: What are you most looking for in this course? A: I'am looking forward to learning more about the earth, there is still a lot more to learn. Q: What are 3 Earth Science related questions you hope to answer in this course? A: 1. Why does the planet have tectonic plates 2. Why do these plates move around? 3. why is B.C known for earthquakes but i have not experienced any major earthquakes in my lifetime? Q: What is your goal for this course and how you going to reach this goal? A: My goal is to stay caught up in class. I miss a lot school due to work. I'm going to try my hardest to hand everything in on time. I'll work on assignments at lunch, homework club and at home to make sure i don't fall behind.
