SCIENCE ASSIGNMENT!!

Category 1

• What rock is light enough to float on water? : Pumice is a volcanic rock that is light enough to float in water.
• Which rocks are formed from the remains of living things? : sedimentary rocks are the remains of living things such as clamshells, plankton skeletons, dinosaur bones, and plants
• Why are the crystals in pillow basalt smaller than those in many other examples of basalt? : pillow basalts where magma is erupted into direct contact with the cold sea form very fast and are therefore small.
• Describe two major differences between the appearance of granite and basalt : granite is a pink/white rock whilst basalt is a dark rock.
• List the three minerals found in granite: mica, plagioclase and feldspar are three minerals found in granite.
• From what are sedimentary rocks formed?: Sedimentary rocks are formed when sediment is deposited out of air, ice, wind, gravity, or water flows carrying the particles in suspension.
• How do you identify sedimentary rocks: Sedimentary rocks generally have a layered appearance.
• Metamorphic rocks: rocks such as gneiss, phyllite, schist, and slate have a layered appearance that is produced by exposure to heat.
• What is a definition: A natural occurring, solid, inorganic element or compound having a uniform composition and a regularly repeating internal structure.
• What is a native element?: Minerals that are composed of atoms from a single element are referred to as native elements. Gold and platinum are examples of native elements.
• Minerals in granite: orthoclase, plagioclase and mica are elements in granite.
• What is an EIS: invironmental impact statement.
• What came after the Stone Age?: the bronze and Iron Age.
• What does a palaeontologist study?: a palaeontologist is a scientist that studies fossils, from tiny bacteria fossils to giant dinosaur fossils.
• In what way where dinosaurs different from mammals?: mammals can survive habitats that dinosaurs can't. Mammals are usually more tame.
• How could meat eating dinosaurs be endangered by the new types of plants?: if herbivores where to eat poisoned plants, they would die which would leave Carnivores with no food.

• What causes the frothy appearance of pumice and scoria?: pumice and scoria are formed by volcanic eruptions, gas forms bubbles in the lava which stays there after it solidifies.
• How can body's of animals be preserved for millions of years?: humans made skeletons to support the large body of a dinosaur so it can stand up. They don't actually have the skin of a dinosaur, they just have the bones.
• What can you learn from a dinosaur footprint?: a dinosaur footprint can tell someone how that dinosaur traveled and acted.
• How can we tell what a dinosaur from millions of years ago ate, slept and traveled?: scientist can tell if that dinosaurs where fast because there thighs would be small but their feet would be big.

Category 3

• Explain how you would decide weather an igneous formed as a result of a volcano: if they where found near a volcano that would mean that they came from that volcano.
• Is table salt a mineral?: the proper mineral name for table salt is halite, and scientist would often identify it by tasting it. Salt is composed of two elements: sodium and chlorine.

Category 6

• Even animal droppings can be fossilised:
• A coprolite is fossilized feces. Coprolites are classified as trace fossils as opposed to body fossils, as they give evidence for the animal's behaviour (in this case, diet)
• They were first described by William Buckland in 1829. Prior to this they were known as "fossil fir cones" and "bezoar stones". They serve a valuable purpose in paleontology because they provide direct evidence of the predation and diet of extinct organisms.

First 24 hours of asteroids falling

• When the asteroids hit the ground shook, the noise was so loud that you couldn't even hear yourself talking. 6 hours in and you can hardly walk 200 meters without running into a crater in the ground. 12 hours in and there are less asteroids falling, which resulted to the ground shaking less. When the day is finally over there is no building or man made structure anywhere, everything is silent the only thing you can hear is the wind and the crackling of fire.
