Okay, these are my last questions of the day....

1. After a rock layer is eroded, which additional event must occur to create an unconformity, or a gap in the geologic record?

an earthquake or motion along a fault
new deposits of sediment must build up on the eroded area
folding of sedimentary rock layers
a volcanic eruption

2. If you wanted to consult the geologic time scale for when the first vertebrates evolved, where would you look?

in the section for the Ordovician period of the Paleozoic era
in the section for the Quaternary period of the Cenozoic era
in the section for the Triassic period of the Mesozoic era
in the section for Precambrian time

3. Earth’s atmosphere, oceans, and continents began to form during the first several hundred million years of

Precambrian time.
the Paleozoic era.
the Mesozoic era.
the Cenozoic era.

4. During the Devonian period, animals that could live on land began to evolve. These animals still spent part of their lives in the water. What were these animals called?

trilobites
reptiles
amphibians
dinosaurs

5. Which of the following events occurred during the Mesozoic era?

Dinosaurs became common on land.
Whales and dolphins evolved in the oceans.
Flowering plants flourished.
The supercontinent Pangaea formed.

My answers:
1.B
2.?
3.?
4.c
5.A

Yup, Connections academy has some hardball tests. It'd be fine, if they actually had TEXTBOOKS this year. I'm not going to watch fifty different videos and activites just to learn when the lizards evolved. Murica'

Riiight??? Connections can be a pain...

Can someone plz help me?

@Princess Anna did you get the answers for this test i'm stuck on it too

Connections Academy? I'm stuck on this test, too.

1. is C the folding of sedentary layers.

You're right on 4. and 5.

yep but i just wish it's wasn't soooooo hard for me also i'm stuck to

lol @Person

There is 17 qustions

Here are the explanations to help you find the answers to your questions:

1. To create an unconformity, or a gap in the geologic record, new deposits of sediment must build up on the eroded area. This means that the correct answer is option B, as an earthquake or motion along a fault, folding of sedimentary rock layers, or a volcanic eruption do not necessarily create an unconformity.

2. To find when the first vertebrates evolved on the geologic time scale, you would need to consult the section for the Ordovician period of the Paleozoic era. This is because the Paleozoic era is the era in which the first vertebrates appeared, and the Ordovician period specifically marks the time when this occurred. Therefore, the correct answer is option A.

3. The correct answer for when Earth's atmosphere, oceans, and continents began to form is Precambrian time. This is because the Precambrian time refers to the vast majority of Earth's geologic history before the Paleozoic, Mesozoic, and Cenozoic eras. During this time, the basic processes that formed the atmosphere, oceans, and continents took place. Therefore, the correct answer is option A.

4. The animals that evolved during the Devonian period and could live on land but still spent part of their lives in the water are called amphibians. This is because the Devonian period is known as the Age of Fishes and marks the transition from aquatic life to terrestrial life. Amphibians were the first group of animals to accomplish this transition. Therefore, the correct answer is option C.

5. Among the events listed, the one that occurred during the Mesozoic era is that dinosaurs became common on land. This is because the Mesozoic era is known as the Age of Dinosaurs, during which dinosaurs were the dominant land creatures. Therefore, the correct answer is option A.

So, your answers are:
1. B
2. A
3. A
4. C
5. A

1)B

2)C
3)A
4)C
5)A
They are all right
