What are five pieces of evidence that the continents used to be all connected?
There are truly only two: 1. The continents fit together like a puzzle 2. There are animal and plant species (extinct or extant) present on separated continents
What continents fit together like a puzzle?
Africa and SouthAmerica because they used to be part of a huge land 200 million years ago called Pangaea the land mass started separating. The pieces slowly drifted apart.Today they are now seven continents
What Two continents are similar in physical outlined shape?
Africa and South America are similar in physical outline shape. This resemblance is due to the way these continents used to fit together as part of the supercontinent Pangaea.
Where continents were formed?
All the continents used to be one large landmass. It was called Pangea. Later on, the landmass started drifting apart little by little. Eventually they became continents.
Was pangaea a perfect fit?
No, Pangaea was not a perfect fit. While the continents formed a single landmass approximately 300 million years ago, there were still gaps and overlaps between them. Scientists have used evidence like matching geological features and fossil records to show that the continents were once connected.
What are two forms of evidence used to support the continental drift theory?
The first one is fossils and the second is the unusual jigsaw puzzle of the continents when they were put together.
What are 5 factors wegener used to support his theory of continental drift?
1. The continents fit together, like a jigsaw puzzle. 2. Similar plant and animal fossils. 3. Large ice sheets. 4. Tropical plants. 5. Scratches on the rocks.
What were the three things that Alfred wegener used to prove the theory of continental drift?
Alfred Wegner had 4 theory`s,Climate evidence,Fossil evidence,the continents fitting together like a puzzle,and horizontal movement. The fossils were different types of ancient ferns and Dinosaurs.
What were the five things used to support Alfred wegenar theory?
Fossil evidence of similar species on separate continents. Geological evidence of matching rock formations and mountain ranges on different continents. Paleoclimatic evidence of past climates that align when continents are placed together. Oceanic ridges and trenches suggesting seafloor spreading. Geographic fit of the continents like a jigsaw puzzle.
What do you call where the continents pushed together?
The theory that the continents used to be one single land mass all "pushed together" is called pangaea
What are five pieces of evidence that the continents used to be all connected?
There are truly only two: 1. The continents fit together like a puzzle 2. There are animal and plant species (extinct or extant) present on separated continents
Why are tectonic plates like the pieces of jigsaw puzzle?
The plates have different shapes, and they all fit together like a jigsaw puzzle. They are like puzzle pieces because many years ago, they used to be joined and then they parted. On the other hand, unlike puzzle pieces, some plates are being pushed underneath other plates (usually oceanic under continental), and new crust is being formed at spreading rifts.
What is a jigsaw used for?
A jigsaw is used for cutting curved or round holes. With a straight guide it can cut straight lines.
Can pva be used as puzzle glue?
If this means to stick a jigsaw puzzle together, then YES, PVA or white glue is best.
Is jigsaw an adjective?
No. A jigsaw is a type of cutting tool that can make complex turns and curves. It is used as an adjunct in terms such as "jigsaw puzzle."
Why is a jigsaw puzzle called that?
Jigsaw means, "Vertically reciprocating saw" (The saw used to cut the jigsaw). Jig is American English for "rapid up-and-down motion".
Why are tectonic plates like the piece of a jigsaw puzzle?
The plates have different shapes, and they all fit together like a jigsaw puzzle. They are like puzzle pieces because many years ago, they used to be joined and then they parted. On the other hand, unlike puzzle pieces, some plates are being pushed underneath other plates (usually oceanic under continental), and new crust is being formed at spreading rifts.
