Matching coastlines and land formation created by glaciers are the two evidence that suggests that Africa, Antarctica, South America, India, and Australia formed Gondwana land 200 million years ago
Further Explanation:
Earth is being marked by almost five ice ages namely Huronian, late Paleozoic, Andean- Saharan, Cryogenian, and the latest one Quaternary Ice age. Well established earliest ice age rocks are called Huronian that is expected to be formed around 2 billion years ago during Proterozoic eon. Cryogenian has existed around 700 million years ago while the late Paleozoic age existed around 300 million years ago. Though the glacial period ended 8,000 years ago its effect is felt still today as its weight was so great that it led to the deformation of earth’s crust and mantle. During deglaciation sea level also rose and that resulted in the sudden shifting of the hydration system and coastline.

The statement that is not true of greenhouse gases is :
They are produced solely by human activities
Human activities such as: using hairspray, creating pollution, etc are worsened the condition of the greenhouse effect, it exists even before we did those things.
Explanation:
Emissions of gases by humans began to rise dramatically because of the economic Revolution and changes in land use. Several greenhouse gas emitting activities area unit currently essential to the worldwide economy and a elementary a part of trendy life.
Carbon dioxide from the burning of fossil fuels is that the largest single supply of gas emissions from human activities.
Though humans are the main cause of greenhouse effect.
Claim: No tools to discover the impending Cell Theory.
Reasoning:
Schleiden and Schwann, as well as Virchow, are generally seen as the founders of the cell theory, due to their pioneering scientific work in the 1800s. The unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells.
Evidence: The cell theory has many complexities and is of importance due to its affect to nearly every aspect of biology, from our comprehension of life & death, managing diseases, cycles and etc. But early scientists had no tools to study cells. They didn't even know about them. It took the invention of the microscope to view them and to begin an understanding of cells.
(Two Dutch spectacle-makers and father-and-son team, Hans and Zacharias Janssen, create the first microscope.) Matthias Schleiden observed that all plants were made of cells from the microscope and Theodor Schwann observed that all animals were also made of cells. Rudolf Virchow observed that cells only come from other cells Virchow saw cells dividing and added that living cells arise only from other living cells. These ideas led to cell theory, which states that all organisms are made of cells, all life functions occur in cells, and all cells come from other cells.
