Question

In a series of rock layers, a geologist finds fossilized shellfish and bony fish in layers that are 1.0 m and 1.5 m deep. However, in a layer that is 2.0 m deep, he finds fossils of a lizard-like dinosaur and a fern-like tree.

Which explains his findings?

A.
An asteroid hit the area, causing the dinosaur to become extinct.

B.
The continent shifted to a polar region.

C.
The ancient land area was invaded by a sea.

D.
The ancient sea dried up and became land.

Answer 1

@Abbiegalie223489

Answer 2

C sounds like it would be the best answer, notice how the layers with the fish and shellfish comes before the layer with the fossilized dinosaur and fern-like tree. Meaning that this layer is above the other one. So I would say that the land was invaded by sea. The law of superpostition says that the rocks that are the highest are the youngest and the ones that are the deepest are the lowest.

Answer 3

Which characteristic is common to all minerals?

A.
They are organic.

B.
They have the same chemical compositions.

C.
They are naturally occurring.

D.
They have an amorphous structure.

Answer 4

C

Answer 5

Minerals are natural occurring yeah, because they can be both inorganic or organic, don't have to have n amorphous structure and don't all share the exact same chemical compositions

Answer 18

Which is the correct explanation for 40°N latitude?

A.
all positions along a circle that runs perpendicular to the equator and 40° east of it

B.
all positions along a circle that runs parallel to the equator and 40° south of it

C.
all positions along a circle that runs parallel to the equator and 40° north of it

D.
all positions along a circle that runs perpendicular to the equator and 40° west of it

Answer 19

This would be c, latitude tells you the position along the equator. It is horizontal or parallel. 0 degrees is the equator and the since this problem says 40 degrees north that means that all position along a circle 40 degrees north parellel to the equator

Answer 20

What type of pressure system is represented by the H on this map, and what kind of weather is a likely result?

Answer 22

H stands for high pressure and high pressure results in fair weather so I would say D for this question. Low pressures,L, can mean increased cloudiness, low temperatures and rain.

Answer 23

Got it?

Answer 32

which is what it is sometimes called.

Answer 33

What patterns in the magnetism of the rocks along the oceanic ridges explain seafloor spreading?

A.
The magnetic patterns periodically reversed only on one side of the ridge.

B.
The magnetic patterns showed only one direction but were symmetrical on both sides of the ridge.

C.
The rocks on one side of the ridge were aligned in one direction, while the rocks on the other side of the ridge were aligned in the opposite direction.

D.
The magnetic patterns periodically reversed and were symmetrical on both sides of the ridge.

Answer 34

A., this answer describes magnetic reversal, at times Earths magnetic, North and South poles reverse and as the ocean spreads the ridges appear as bands of alternating magnetic fields.

Answer 35

*the reversals** not the ridges.

Answer 36

Which is an accurate description of sandy soil?

A.
low porosity, moderate permeability

B.
moderate porosity, moderate permeability

C.
low porosity, high permeability

D.
high porosity, low permeability

Answer 37

come on i need help

Answer 38

@Abbiegalie223489 and @gage224 you are not supposed to give the answers you are supposed to explain it

Answer 39

I think since it is sandy that would mean low porosity however since it is soil I guess that would mean high permeability.

Answer 40

@_fluffeh_ I'm sorry about that!! I was trying to give my answer and explain why I chose that particular choice. I'll just explain it from now on

Answer 41

@Abbiegalie223489 it is perfectly fine :) just explain and try your best not to give the answer

Answer 46

she said nothing wrong
I can still help you by explaining what the question is asking. And it's better that i do it like that because you'll learn better if you form your on conclusion on which one is correct.

Answer 47

*own

Answer 48

then help me

Answer 49

yeah I am typing my explanation right now

Answer 50

Latitude is vertical distance form the equator, having a high latitude means that it is located north. If iceland is by an ocean that could help influence a milder climate

Answer 51

Sorry about all the typos today

Answer 53

In which period on the geological time scale were the dinosaurs dominant?

A.
Devonian

B.
Quaternary

C.
Triassic

D.
Cambrian

Answer 54

can you just tell me the answers please i'm running late

Answer 55

That would be wrong to do, I an type faster though and try not to make lengthy explanations

Answer 56

The cambrian period began around 543 million years ago and it had prehistoric life.
Triassic era was one of major extinction.

Answer 57

Quantenary era is our current era

Answer 58

And the devonian era is known as the age of fishes

Answer 59

Do you think you have an idea of what the answer could be?

Answer 60

the triassic era is known as the age of "reptiles" but not dinosaure

Answer 61

*dinosaurs

Answer 62

@Abbiegalie223489

Answer 63

In terms of density and humidity, which conditions characterize a low-pressure area?

A.
high density, low humidity

B.
low density, low humidity

C.
high density, high humidity

D.
low density, high humidity

Answer 64

@pooja195

Answer 65

High pressure areas compress air to the center of the area this makes high density. It has cooler air. Lower pressure areas do the opposite of this they have low density and rising, warm air.

Answer 68

Which type of weather is most likely produced by a stationary front?

A.
moderate to heavy precipitation

B.
no precipitation

C.
grey skies and/or precipitation lasting a long time

D.
heavy precipitation and thunderstorms

Answer 69

@Abbiegalie223489

Answer 70

Hurry up please

Answer 71

there are different types of front kinds that bring warm air and kinds that bring cold air. When a cold front or warm front stops moving, like lets say that because it's changing it's direction, it is a stationary front. They are usually associated with cold temperatures and can result in flooding, and heavy amount of precipitation so thunderstorms

Answer 72

*fronts

Answer 73

is it b

Answer 74

it is?

Answer 75

the answer should involve one with heavy precipitation that describes cold weather maybe thunderstorms too since that is associated with stationary fronts

Answer 76

*be one

Answer 77

Just give me the answers goshh

Answer 78

Which information is represented by a line on this map?



A.
points with the same elevation

B.
the location of a road

C.
a direction east or west

D.
a direction north or south

Answer 79

I think it would be c. because grey skies are like a major symbol of stationary fronts.

Answer 80

^ on the other question

Answer 81

Which location on this map has the lowest elevation?



A.
Coolage Lake

B.
the houses in the center of the map

C.
Mount Cleveland

Answer 83

elevation is height so using the contour lines look at the number that is the lowest to find which location on that map has the lowest elevation

Answer 84

And for your other question that asked what the lines on this map represent, i think my answer above should help you form a conclusion for that

Answer 85

Is that the last question you have?
