Are you ready? Let’s play Who Wants To Be A Scientist ? Are you ready? Let’s play The breaking down and wearing away of rock by atmospheric forces is called? deposition erosion weathering subduction A B C D

The Answer is weathering C Natural weathering breaks up rocks into smaller pieces forming sediments.

Who Wants To Be A Scientist ? Next question. What are large, heavy slabs of ice that move back and forth across the land depositing weathered rocks and sediments over time called? hail icicles glaciers icebergs A B C D

The Answer is C glaciers Glaciers are sheets of ice which move like rivers slowly over the land carving up rocks and sediments as they advance and recede.

Who Wants To Be A Scientist ? Next question, Which process moves sediments away from one place to another place? deposition erosion weathering expansion A B C D

The Answer is erosion B Erosion takes away the land in one place and builds land in another, moving weathered rock sediments by wind, water, ice or gravity.

Who Wants To Be A Scientist ? Next question please Which event suddenly releases waves of energy through the Earth moving huge slabs of crust? volcanoes weathering erosion earthquakes A B C D

The Answer is D earthquakes Earthquakes shake and shift the crust as slabs of the Earth move against each other under the surface.

Who Wants To Be A Scientist ? The next question is What kind of rock forms when matter deposited in layers becomes cemented together? sedimentary depository igneous metamorphic A B C D

The Answer is A sedimentary Sedimentary rocks form when pieces of rocks, minerals and the remains of living things are cemented together by water into new rock layers.

Who Wants To Be A Scientist ? New question. Which shows the correct order of events in the formation of igneous rock? weathering, erosion deposit, cementation melting, magma, cooling, hardening squeezing, heating melting, cooling hardening, magma A B C D

The Answer is B melting, magma, cooling, hardening Igneous rock is born of fire and volcanic activity and forms when magma or lava cools and becomes solid.

Who Wants To Be A Scientist ? Next question please Which type of rock is most likely to contain fossils? mineral igneous sedimentary metamorphic A B C D

The Answer is C sedimentary Fossils are the remains or traces of organisms that lived in the past. Over time organisms die and are covered with sediments which are eventually cemented together forming layers of sedimentary rock.

Who Wants To Be A Scientist ? Next question What type of rock forms between a plate boundary when magma wells up and hardens? fossil igneous sedimentary metamorphic A B C D

The Answer is igneous B Plate boundaries are places where lava escapes from the mantle of the Earth. As lava cools it forms new igneous rocks.

Who Wants To Be A Scientist ? Next question, Which black, glassy rock forms when lava rapidly cools in the water after a volcanic eruption? granite slate obsidian marble A B C D

Obsidian is an igneous rock formed when lava super cools in the water. The Answer is obsidian C Obsidian is an igneous rock formed when lava super cools in the water.

Who Wants To Be A Scientist ? Next question Which change in the weather would most likely result in some erosion? precipitation temperature air pressure humidity A B C D

The Answer is A precipitation Rain is a form of precipitation that moves sediments from one place to another causing errosion.

Who Wants To Be A Scientist ? And the next question is Which tool helps you see small pieces of matter? compass ruler scale magnifying glass A B C D

The Answer is magnifying D glass A magnifying glass has a concave lens that refracts light making objects appear bigger.

Who Wants To Be A Scientist ? Next question please. This landform consists primarily of what type of rock? fossil sedimentary metamorphic igneous A B C D

Volcanic activity forms igneous rock land formations. The Answer is igneous D Volcanic activity forms igneous rock land formations.

Who Wants To Be A Scientist ? And the next question is Which phase of the Moon is visible at night when the Sun, Earth, and Moon form a straight line? new moon crescent full moon gibbous A B C D

The Answer is C full moon Both the new and full moons phases occur when the Sun, Earth and Moon form a straight line, but only the full moon phase is visible in the night sky.

Who Wants To Be A Scientist ? Next question, Why does the Moon shine brightly in the night sky? It reflects light from the Sun from the Earth It produces its own light volcanic eruptions on the moon A B C D

The Answer is It reflects light A from the sun The moon doesn’t make any light of its own. The light we see is sunlight that hits the moon and is reflected to Earth.

Who Wants To Be A Scientist ? Here is your next question. The moon causes which of the following natural events on the Earth? night and day seasons tides erosion A B C D

The Answer is tides C The moon’s gravitational pull on the Earth causes the ocean tides on the Earth. Tides can cause erosion.

Who Wants To Be A Scientist ? Next question, Which is an effect of the 23.5 degree tilt of our Earth on its axis? day and night the seasons gravity ocean tides A B C D

The Answer is B the seasons Earth’s tilt causes different seasons to occur in the northern and southern hemispheres.

Who Wants To Be A Scientist ? Next question, Which property is least useful for identifying a mineral sample? luster hardness color streak A B C D

The Answer is color C Most minerals can occur in a variety of colors, so color is not a reliable test for identifying a mineral sample.

Who Wants To Be A Scientist ? Next question, What are Earth and all the other planets in the solar system constantly doing? shrinking glowing moving vibrating A B C D

The Answer is moving C Earth and all the planets rotate and orbit around the sun and are constantly in motion.

Who Wants To Be A Scientist ? New question, The spinning motion of Earth is called rotation. Exactly how long does it take the Earth to complete one rotation on it axis? 23 hours, 56 minutes 356 days, 16 hours, 6 minutes 29.5 days 24 hours, 37 minutes A B C D

The Answer is 23 hours, A 56 minutes Earth actually makes one rotation on its axis in just under one day. We round up to 24 hours for practical time keeping on Earth. Mars takes just over 24 hours to make one rotation, or day, on Mars.

Who Wants To Be A Scientist ? Next question, As longer summer days become shorter in the fall and winter months in North America, what happens to the available solar energy? it increases it’s the same nothing it decreases A B C D

The Answer is D it decreases Less sunlight means less available energy so temperatures decrease in the northern hemisphere in the fall and winter months.

Who Wants To Be A Scientist ? Next question, During which season are the sun’s rays the most direct in the northern hemisphere? summer fall winter spring A B C D

The Answer is summer A Although Earth is furthest away from the sun in its orbit in the summer, the northern hemisphere gets the most direct sunlight and available solar energy in the summer season because Earth is tilted on its axis

Who Wants To Be A Scientist ? Next question, What is the path of Earth’s revolution around the Sun called? rotation orbit trek journey A B C D

The Answer is orbit B An orbit is the path an object takes around another object in space. Planets orbit stars and moons orbit planets.

Who Wants To Be A Scientist ? Your next question, How long does it take for Earth to make one orbit around the Sun? 24 hours 365.25 days 29.5 days 9 months A B C D

The Answer is 365.25 days B One Earth orbit, or year, takes exactly 365 days, 6 hours, and 16 minutes. We round down to 365 days for practical time keeping and add one day, “leap day in leap year”, every 4 years to adjust our calendars.

Who Wants To Be A Scientist ? Next question, Which of the following factors causes the change of seasons on the Earth? the tilt of Earth’s axis the length of Earth’s orbit the distance from Earth to the Sun the length of day and night A B C D

The Answer is the tilt of A Earth’s axis The Earth’s tilted axis causes the change of seasons in the northern and southern hemispheres. Both the length of day and night and change in temperatures are effects of the tilt.
