Central America is the southernmost, isthmian portion of the North American continent, which connects with the South American continent on the southeast. hope this helps :)
Answer:
The climate in that area is different today than when tropical plants and animals lived there
Explanation:
The most likely reason for the absence of those tropical animals in North Texas would be the climate.
Climatic conditions have varied through geologic history of our blue planets. When these conditions changes, organisms have to adapt and on the long run, the environment won't be able to sustain them. They become phased out.
It is possible for rock records in a place to bear different fossil records records that are not similar compared to the life we have in such areas today.
The Sahara desert for example has huge fossils of fishes in its rocks. Today, the area is a hot desert and contains very low biodiversity. Sciencist have proposed that the region was previously a lush green tropical forest and the ocean covered some parts too. Today, the Sahara's climate has changed.
Explanation:
Lava Cools on the side of a volcano
Storms erode the hardened lava
Particles of hardened water settle at the bottom of lakes
Layers of sediments bond underwater
Plate movement bakes sedimentary layers.
Since the transition is from igneous to sedimentary to metamorphic rocks;
- Lava which is magma or molten rock that reaches the surface cools and solidifies to form a volcano.
- Weathering and erosion of the volcano then proceeds and sediments are formed
- The sediments are further carried underwater where they harden at bottom of lakes.
- Layers of the sediments bond and cements together underwater to form sedimentary rocks.
- Tectonic activities further bakes the layers to form metamorphic rocks.
I know 6 is multiplying by 3 but idk the other ones
