ANSWER:
b. Similar fossils of plants and animals are found on widely separated continents.
c. Remains of tropical plants found in Antarctica.
d. Matching jig-saw puzzle coastlines, particularly with the west coast of Africa and east coast of South America.
EXPLANATION:
Continental drift is the earliest ways geologists believed continents moved gradually. The continental drift theory is connected to the scientist Alfred Wegener. He was certain that all continents of the Earth were once fragment of a mammoth, single land form known as 'Pangaea'. Wegener a trained astronomer, used botany, geology, and biology to define Pangaea and the continental drift.
For instance, fossils of the primeval reptile Mesosaurus, a freshwater reptile,were only found in South America and Southern Africa and Mesosaurus being only one meter long would not have swam the Atlantic Ocean. The existence of Mesosaurus suggested a single habitat with several rivers and lakes. Wegener studied fossils of plants from the glacial Arctic Svalbard Archipelago, Norway.
These plant fossils were not the sturdy specimens accustomed to subsist in the Arctic climate. These fossils were that of the tropical plants, which adapts to a more humid, much warmer environ. The existence of these fossils submits Svalbard once had a tropical climate.Lastly, Wegener studied the stratigraphy of mountain ranges and different rock.
Africa's West-Coast and South America's East-Coast fit together like jigsaw puzzle pieces, and Wegener learnt their rock layers fit very clearly. Wegener uncovered that the Eastern United States' Appalachian Mountains, for example, were geologically connected to Scotland's Caledonian Mountains.
The correct options are A) Remains of tropical plants have been found in Antarctica, C) Mountain ranges in North America match up with those along the European coastline. and D) Similar fossils of plants and animals are found on widely separated continents.
What evidence suggests the continents were once all together but then drifted apart?
Mountain ranges in North America match up with those along the European coastline. Similar fossils of plants and animals are found on widely separated continents. Remains of tropical plants have been found in Antarctica.

ASAP plz Which statement best describes how the Great Rift Valley in Africa formed?
The rift valley formed when the crust pulled apart.
The rift valley formed due to subduction.
The rift valley formed similarly to an island arc.
The rift valley formed at a convergent boundary
Answer:
The rift valley formed when the crust pulled apart.
Explanation:
The Great Rift Valley in Africa is a rift valley that stretches across the eastern part of the continent, though regionally it passes through Eastern, Central, and South Africa. It is the longest rift valley in the world, and it is constantly becoming wider and wider. To not be confused, this rift valley is not just one line cutting through the continent, but it has divisions that are connected to it.
The reason for the formation of the Great Rift Valley is the divergent boundary that has formed in this part. This divergent boundary has cracked open the crust of the African plate, now dividing it into two separate plates, the Nubian plate, and the Somali plate. Now, these two plates are moving away from each other, and over time, as the gap between them grows, the seawater will fill in the space between them, physically separate them, and give rise to a new sea which will later become an ocean.
Answer:
A) The rift valley formed when the crust pulled apart.
Explanation:
Today, the term is most often used to refer to the valley of the East African Rift, the divergent plate boundary which extends from the Afar Triple Junction southward across eastern Africa, and is in the process of splitting the African Plate into two new separate plates.

Which of these is not an advantage of wetlands?
Group of answer choices
recharge water tables
help prevent flooding
flow rapidly
good habitat for life
Answer: Low rapidly
Explanation:
Wetlands are areas that are filled with water sometimes permanently, sometimes seasonally. They have a couple of advantages such as recharging water tables, preventing flooding and providing a good habitat for life.
They recharge the water table by collecting water then letting it sip into the ground mostly at the edges. They prevent flooding by also collecting water then letting the water out gradually. They provide a good habitat for life as wetlands are teeming with fish, animal and plant life.
A rapid flow is therefore not an advantage of wetlands.

The ice lobe that formed the statewide trough of the Minnesota River was the last of several that entered Minnesota during the last period of glaciation. Ice lobes were dynamic tongues of ice that extended far south of the main ice sheet and in contrast to the glacial ice sheet that moved slowly, ice lobes advanced quickly and then stopped. Elaborate on how such an ice lobe may be responsible for the formation of the Minnesota River.
A) The ice lobes advanced and stopped many times, eroding the land to create a trough and then filled it with draining water from the ice sheet that was feeding them.
B) There was no true drainage valley for the melting glaciers and multiple small streams flowed from north to south. Eventually they merged, forming the Minnesota River.
C) Beneath the till of the Des Moines ice lobe lie layers of older glacial units from previous glaciations; these layers vary in thickness and when they melted, formed the Minnesota River.
D) Outwash plains contained large amounts of glacial till that eroded the land and one area was the trough of the Minnesota River. Eventually the waters of the outwash plain filled the trough.
Answer:
A) The ice lobes advanced and stopped many times, eroding the land to create a trough and then filled it with draining water from the ice sheet that was feeding them.
Explanation:
The creation of the Minnesota rover started when the bottom was an oversized valley having its roots in the ice ages when the glacier repeatedly moved 2 to 10,000 million years ago. For about 120-150,000 years ago the ice sheets formed by the lobes of ice in Minnesota and it was covered by moraine and glacial deposits.Why is Baja California splitting away from mainland Mexico?
Which of the following is true of the Antarctic Treaty System?
A. It allows limited weapons testing of the continent.
B. It limits restrictions of environmental controls.
C. It encourages scientific research.
D. Members came from the Antarctic Agreement.
Answer:
The Antarctic Treaty System encourages scientific research.
Explanation:
The Antarctic Treaty has been put in place in order to prevent escalation of the situation during the past century, but also to prohibit any violence and military interventions in the continent. Numerous countries rushed to take their piece of Antarctica with the goal of taking as much as possible for further exploitation. This led to a lot of tensions, so luckily all sides set at a table and solved the problems in a diplomatic manner.
There are a lot of articles in the treaty, but one of the most important ones is the one that focuses on science. This treaty supports scientific research and encourages the countries to do so. Not just that, but it encourages collaboration between the countries in their scientific teams in order for them to get closer and to work for mutual and global interest.

What is migration?Human migration is the movement of individuals from one location to another with the aim of relocating, either permanently or temporarily. Internal migration is also a possibility; in fact, it is the most common type of human migration internationally.
The movement frequently takes place over great distances and from one country to another. Migration is frequently linked to improved human capital, both at the individual and household levels, as well as improved access to migration networks, which might help with a potential second move.
Migration is the most direct path out of poverty, according to certain research, and it has a tremendous potential to boost human development.
Age plays a role in both work-related and non-work-related migration. Migration can occur in small groups, extended families, or single individuals.

Pablo wants to know the stage of the democratic transition model that his grandparents’ home country is currently at. The mortality rate has been slowly declining for a couple of decades. The fertility rate is still higher than in the most developed countries, but it is beginning to decline as well. What stage would this represent?
Stage 1
Stage 2
Stage 3
Stage 4
Answer:
Pablo's grandparents' home country is in Stage 3 of the demographic transition model.
Explanation:
Stage 1; is not correct because in this stage the mortality rates are very high, and the fertility rates are also very high.
Stage 2: is not correct because in this stage the mortality rates are still relatively high, while the fertility rate is the highest.
Stage 3: is correct because in this stage the mortality rate is at a medium level, thus declining, while the fertility rates have declined but are still on a good level.
Stage 4: is not correct because in this stage the mortality rate and the fertility rate are both relatively low, they equalize at the end of this stage, and the population stagnates or has just a very small growth.
