Sedimentary rock is most likely to contain fossils. Fossils are the remains of once-living organisms. The sediments that make up sedimentary rock often include the remains of plants and animals.
Which type of rock most likely contains fossils?
There are three main types of rock: igneous rock, metamorphic rock, and sedimentary rock. Almost all fossils are preserved in sedimentary rock.
Which type of rock contains fossils quizlet?
Sedimentary rocks are the only rocks that contain fossils and therefore, a record of ancient life.
Which of the following would most likely contain fossil?
A fossil would most likely contain in organic sedimentary rock.
Which rock is most likely a sedimentary rock quizlet?
The most common sedimentary rocks are fragmental, or clastic, rocks.
What do all rocks have in common?
What do all rocks have in common? They all have the same color. They all have minerals. They all have the same shape.
What rocks are fossils found in?
Most fossils “hide out” in sedimentary rock . When tiny bits of rocks and minerals (called sediment) join together over millions of years, they become sedimentary rock. Plants and animals that become sandwiched in this sediment eventually turn into fossils. Two examples of sedimentary rocks are sandstone and shale.
What type of rock is made from heat and pressure?
Metamorphic rocks start as one type of rock and—with pressure, heat, and time—gradually change into a new type of rock.
Why can volcanic rocks occasionally contain fossils?
Fossils are organic products which are preserved in the Earth’s crust. … Obviously, magma and lava can’t contain any life forms because they come from the deepest and hottest places on the Earth where life is impossible. That’s why fossils can’t be found in the igneous rocks.
Which two rocks contain the mineral quartz?
Answer: Quartz is among the most common of all rock forming minerals and is found in many metamorphic rocks, sedimentary rocks, and those igneous rocks that are high in silica content such as granites and rhyolites.
What do fossils tell us?
Fossils are the remains or traces of ancient life that are usually buried in rocks. Examples include bones, teeth, shells, leaf impressions, nests, and footprints. This evidence reveals what our planet was like long ago. Fossils also show how animals changed over time and how they are related to one another.
Can metamorphic rocks contain fossils?
Sorry – no fossils here! Metamorphic rocks have been put under great pressure, heated, squashed or stretched, and fossils do not usually survive these extreme conditions. … Generally it is only sedimentary rocks that contain fossils.
Which rock cools the fastest?
The difference between an Extrusive and Intrusive igneous rock is the way in which they cool. The inside of the Earth is very hot – hot enough to melt rocks. Lava cools fastest at the earth’s surface, while magma, which cools more slowly, can form larger mineral crystals.
Which minerals contain the two most?
Silicates. Silicate minerals contain silicon (Si) and oxygen (O), the two most abundant elements in the earth’s crust.
Which rock is least likely to contain fossils?
Rocks that has vital nutrient and conducive environment to nurture life contain fossils. Granite is the only rocks least likely among the option that can harbor life and invariably contain fossil due to the mode of formation. Granite is an intrusive igneous rocks .
Which type of rock is likely to show ripple marks and fossils?
Sedimentary structures are the larger, generally three-dimensional physical features of sedimentary rocks; they are best seen in outcrop or in large hand specimens rather than through a microscope. Sedimentary structures include features like bedding, ripple marks, fossil tracks and trails, and mud cracks.
