How has the movement of plates affected the evolution of living things?
As Pangaea split into the 7 continets, the types of animals got separated with their homeland, so they changed their traits to survive in the new environment over time.
How does the motion of the tectonic plates affect the distribution of organisms?
New species can become isolated to specific regions, changing the environment they live in, which will change the traits they earn.
How could you explain why glacial deposits are found in areas where no glaciers exist today?
Pangea was a super continent and that was a time when all of the continents were joined together. when Pangaea broke apart, they moved to different locations which are different climate zones so glaciers no longer existed in places where the climate changed from cold to hot.
What was the landmass called that existed nearly 200 years ago?
All of the continents that existed 200 years ago are still in existence (though their current names may have changed from the past.) Geologically speaking, 200 years passes in a blink of an eye. It takes thousands of years for landmasses to undergo significant changes.
What cells cause the cuttlefish to be able to blend in with its surroundings?
Chromatophores They are most notable in brightly colored squid, cuttlefish and octopuses. Each chromatophore unit is composed of a single chromatophore cell and numerous muscle, nerve, glial and sheath cells. Inside the chromatophore cell, pigment granules are enclosed in an elastic sac, called the cytoelastic sacculus. To change color the animal distorts the sacculus form or size by muscular contraction, changing its translucency, reflectivity or opacity. This differs from the mechanism used in fish, amphibians and reptiles, in that the shape of the sacculus is being changed rather than a translocation of pigment vesicles within the cell. However a similar effect is achieved.
How has earth changed from Pangaea to present?
it grew people
What animals moved to land and changed into reptiles?
The reptiles ancestors
Did Pangaea change the earths shape?
No! pangea changed the sufaces of the earth not the shape
How did the break up of pangaea affect land organisms during the mesozoic era?
When Pangaea broke up, species had to adapt to changing environments. Those species that could adapt, changed along with their habitats. Those that could not adapt died off.
How has earths appearance changed since pangaea?
the continents have broken up from the continental drift
Which continent changed its position least since Pangaea?
Antarctica is the continent that changed its position the least since Pangaea. It has remained relatively close to its original location near the South Pole throughout geological time.
Where are frogs from?
Over 400,000,000 years ago, fish which were probably the most advanced life forms lived in the water. Until then, plants and insects occupied the land alone. Most all amphibians have features and characteristics of fish and reptiles. Some of the most common amphibians are frogs, toads, and salamanders. They have changed very little since they first began breathing on land, some of the earliest amphibians were ancestors of today's birds, reptiles, and mammals. The word amphibian comes from the Greek word, "amphi" meaning "both", and "bios" meaning "life". It is describing cold blooded animals that have backbones that can survive both on land and in fresh water. You can find amphibians living on land near ponds, lakes, swamps, and near riverbanks.
Did the formation of pangaea caused the climate on earth to change?
since the location of certain places changed the weather there change to
Do amphibians have a complete metamorphosis?
Yes they do, because they change from a larva to a subadult while their body is changed drastically, especially frogs. They are the only amphibians without a tail after metamorphosis.
What is an evolutionary change in reptiles?
Mainly size is what changed from prehistoric times to today.
What was happening when Pangaea broke into the continents?
When Pangaea broke apart, the tectonic plates underneath the Earth's surface shifted, causing the supercontinent to split up into the continents we have today. This movement of the plates created new oceans and changed the arrangement of landmasses on Earth.
What are the difficulties with positioning the current continents in Pangaea?
Difficulties in positioning the current continents in Pangaea include: Climate variations: Weather patterns and climatic conditions have changed significantly since Pangaea, making it hard to accurately reconstruct the exact positions. Geological shifts: Tectonic plate movements have altered the shape and position of continents, leading to uncertainties in accurately placing them in the Pangaea configuration. Limited data: The further back in time we go, the sparser and less precise the geological and paleontological evidence becomes, introducing uncertainties in reconstructing Pangaea.
