Convection Currents in the Mantle (Asthenosphere)
1. Heat transfer within a fluid takes place by .
2. Scientists think that convection currents flow in Earth’s .
3. Earth’s mantle is a layer of hot, fluid, tar-like that flows slowly.
4. Which layer is made of the crust and the uppermost part of the mantle?
5 Where does the heat come from that drives the convection currents within the Earth?
6. When a fluid gets hot, the particles gain energy, get excited and . The mass stays the same but the volume increases.
7. This slight increase in volume the density.
8. When a fluid cools, the particles lose energy and . The mass stays the same but the volume decreases.
9. This slight decrease in volume the density.
10. Density = m/v Find the density of hot rock with a mass of 20 and a volume of 10.
11. Density = m/v Find the density of hot rock with a mass of 20 and a volume of 8.
12. When a fluid (like hot rocks at the bottom of asthenosphere) is heated, its density , making them rise.
13. When a fluid (like hot rock at the top of the asthenosphere) cools, its density , making them sink.
14. The asthenosphere is part of which layer?
15. Hot rock is more less dense and .
16. Cold rock is more dense and .
17. Scientists hypothesize that convection currents in the move the large tectonic plates of the .

7. using your knowledge of colligative properties explain whether sodium chloride or calcium chloride would be a more effective substance to melt the ice on a slick sidewalk. use 3 – 4 sentences in your explanation. 8. when a 2.5 mol of sugar (c12h22o11) are added to a certain amount of water the boiling point is raised by 1 celsius degree. if 2.5 mol of aluminum nitrate is added to the same amount of water, by how much will the boiling point be changed? show all calculations leading to your answer or use 3 – 4 sentences to explain your answer. 9. if 5.40 kcal of heat is added to 1.00 kg of water at 100⁰c, how much steam at 100⁰c is produced? show all calculations leading to an answer. 10. the freezing of water at 0⁰c can be represented as follows: h2o (l) ↔ h2o(s) the density of liquid water is 1.00 g/cm3. the density of ice is 0.92 g/cm3. in 3 – 4 sentences explain why applying pressure causes ice to melt.
