How does continental drift result in biological evolution?

continents broke apart, species got separated by oceans driving evolution

Why are fossils found in sedimentary rock and not in other types of rock?

Sedimentary rock forms at temperatures and pressures that preserves remains

Which supports the theory that some mountains were once at the bottom of an ocean?

Fossils of marine organisms are found on the tops of some mountains.

How do species variations increase an organism’s chances of survival?

Favorable variations in populations increase probability of survival

How do scientists use fossils as evidence of evolution?

Fossils show how much organisms have changed as life developed on Earth.

How are extinctions of species related to environmental changes?

Species have to adapt to new climate patterns or they may become extinct

Which evidence supports the idea that life on Earth has continually evolved?

evidence from rock layers, fossils, and ice cores

How do we know that Earth has changed over time?

Scientist can study fossils, rocks and plate tectonics to determine change

Answers

1
How does continental drift result in biological evolution?
As continents collide, tidal waves are formed that will drown life
continents broke apart, species got separated by oceans driving evolution
As continents move, they bring with them people who often eat everything
Sometimes continents drift right off of the Earth killing all organic life
2
Why are fossils found in sedimentary rock and not in other types of rock?
All other typed of rocks are too soft
It is too difficult to break-up any other type of rock.
Sedimentary rock forms at temperatures and pressures that preserves remains
Sedimentary rocks are found only in arctic regions with no life forms.
3
Which supports the theory that some mountains were once at the bottom of an ocean?
Freshwater rivers flow to the ocean.
Fossils of marine organisms are found on the tops of some mountains.
There are underwater mountains on the ocean floor today
mountains and ocean floors have similar minerals in their rocks.
4
Which is the most accurate method scientists use to predict the age of Earth?
relative dating of rock layers
comparing the ages of different fossils
investigating core samples from the Arctic
radioactive dating of rocks
5
How do species variations increase an organism’s chances of survival?
Favorable variations in populations increase probability of survival
Some variations of an organism can mutate into giant lizards Monsters
More varieties of a species brings more options for dinner preparation
More variations make it more difficult for a species to adapt
6
How do scientists use fossils as evidence of evolution?
Scientist can determine how many Taco Bells existed
A fossil can only tell scientist where the organism lived
Fossils show how much organisms have changed as life developed on Earth.
To make charcoal for their grills
7
How are extinctions of species related to environmental changes?
As species continue going extinct, their remains disrupt the Carbon Cycle.
As global temperatures go down, more animals are killed by humans
Global warming has caused many species to move to Iceland
Species have to adapt to new climate patterns or they may become extinct
8
Which would most likely increase the genetic variation in a population of organisms?
increase in diseases
increase in mutations
decrease in diseases
decrease in mutations
9
Which evidence supports the idea that life on Earth has continually evolved?
evidence gathered from melting glaciers
evidence from rock layers, fossils, and ice cores
evidence that the climate has changed over the past 100 years
evidence from layers of tree rings
10
How do we know that Earth has changed over time?
Scientist can study fossils, rocks and plate tectonics to determine change
Because Mr. Smith says so!
Scientists track the phases of the Moon and how they react to the Sun.
By studying the how photosynthesis allows plants to create their own food.
