AND NOW IT’S TIME TO TEST YOUR KNOWLEDGE And See
The breaking down and wearing away of rock by atmospheric forces is called? deposition erosion weathering subduction A B C D Are you ready? Let’s play Who Wants To Be A Scientist ?
The Answer is weathering C Natural weathering breaks up rocks into smaller pieces forming sediments.
Next question. Who Wants To Be A Scientist ? 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 glaciers C Glaciers are sheets of ice which move like rivers slowly over the land carving up rocks and sediments as they advance and recede.
Which process moves sediments away from one place to another place? deposition erosion weathering expansion A B C D Next question, Who Wants To Be A Scientist ?
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.
Which event suddenly releases waves of energy through the Earth moving huge slabs of crust? volcanoes weathering erosion earthquakes A B C D Next question please Who Wants To Be A Scientist ?
The Answer is earthquakes D Earthquakes shake and shift the crust as slabs of the Earth move against each other under the surface.
What kind of rock forms when matter deposited in layers becomes cemented together? sedimentary depository igneous metamorphic A B C D The next question is Who Wants To Be A Scientist ?
The Answer is sedimentary A Sedimentary rocks form when pieces of rocks, minerals and the remains of living things are cemented together by water into new rock layers.
New question. Who Wants To Be A Scientist ? Which shows the correct order of events in the formation of igneous rock ? weathering, erosion deposit, cementation melting, magma, cooling, hardening deposit, cementation squeezing, heating melting, cooling hardening, magma A B C D
The Answer is melting, magma, cooling, hardening B Igneous rock is born of fire and volcanic activity and forms when magma or lava cools and becomes solid.
Next question please Who Wants To Be A Scientist ? Which type of rock is most likely to contain fossils ? mineral igneous sedimentary metamorphic A B C D
The Answer is sedimentary C 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.
Next question Who Wants To Be A Scientist ? 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. igneous rocks.
Which black, glassy rock forms when lava rapidly cools in the water after a volcanic eruption? granite slate obsidian marble A B C D Next question, Who Wants To Be A Scientist ?
The Answer is obsidian C Obsidian is an igneous rock formed when lava super cools in the water.
Which change in the weather would most likely result in some erosion? precipitation temperature air pressure humidity A B C D Next question Who Wants To Be A Scientist ?
The Answer is precipitation A Rain is a form of precipitation that moves sediments from one place to another causing errosion.
Which tool helps you see small pieces of matter? compass ruler scale magnifying glass A B C D Who Wants To Be A Scientist ? And the next question is
The Answer is magnifying glass D A magnifying glass has a concave lens that refracts light making objects appear bigger.
Who Wants To Be A Scientist ? This landform consists primarily of what type of rock? fossil sedimentary metamorphic igneous A B C D Next question please.
The Answer is igneous D Volcanic activity forms igneous rock land formations.
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 Who Wants To Be A Scientist ? And the next question is
The Answer is full moon C 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.
Why does the Moon shine brightly in the night sky? It reflects light from the Sun It reflects light from the Earth It produces its own light volcanic eruptions on the moon A B C D Who Wants To Be A Scientist ? Next question,
The Answer is It reflects light from the sun A 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.
The moon causes which of the following natural events on the Earth? night and day seasons tides erosion A B C D Who Wants To Be A Scientist ? Here is your next question.
The Answer is tides C The moon’s gravitational pull on the Earth causes the ocean tides on the Earth. Tides can cause erosion.
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 Who Wants To Be A Scientist ? Next question,
The Answer is the seasons B Earth’s tilt causes different seasons to occur in the northern and southern hemispheres.
Which property is least useful for identifying a mineral sample? luster hardness color streak A B C D Who Wants To Be A Scientist ? Next question,
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.
What are Earth and all the other planets in the solar system constantly doing? shrinking glowing moving vibrating A B C D Who Wants To Be A Scientist ? Next question,
The Answer is moving C Earth and all the planets rotate and orbit around the sun and are constantly in motion.
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 Who Wants To Be A Scientist ? New question,
The Answer is 23 hours, 56 minutes A 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.
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 Who Wants To Be A Scientist ? Next question,
The Answer is it decreases D Less sunlight means less available energy so temperatures decrease in the northern hemisphere in the fall and winter months.
During which season are the sun’s rays the most direct in the northern hemisphere? summer fall winter spring A B C D Who Wants To Be A Scientist ? Next question,
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
What is the path of Earth’s revolution around the Sun called? rotation orbit trek journey A B C D Who Wants To Be A Scientist ? Next question,
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.
How long does it take for Earth to make one orbit around the Sun? 24 hours days 29.5 days 9 months A B C D Who Wants To Be A Scientist ? Your next question,
The Answer is 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.
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 Who Wants To Be A Scientist ? Next question,
The Answer is the tilt of Earth’s axis A 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.
