A Correct answer
Explanation

Fossils are the preserved remains, impressions, or traces of organisms from the past. Paleontologists are the scientists who study them, while strata refer to layers of rock.

Multiple choice

  1. kind of natural resource

  2. living beings

  3. coal mines

  4. Dead remains of living organisms

D Correct answer
Explanation

Fossils are the preserved remains, impressions, or traces of ancient living organisms that have been buried in sediment.

Multiple choice landforms of the earth and internal forces general physical geography general knowledge

Land forms that we see today is the result of millions of years of endogenetic and exogenetic forces working together. With respect to geologic time scale, choose the correct statements.
(1) There have been 9 or more orogenic phases.
(2) Alpine is the most recent geologic period of orogeny.
(3) Caledonian and Hercynian are also a geologic time period of orogeny.
(4) Urals, Pennines, Applachians belong to Hercynian period.
(5) Alps, Himalayas, Andes and Rockies belong to Alpine period.

  1. 1, 3 and 5

  2. 1, 2 and 4

  3. 1, 2, 3 and 4

  4. All of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

All statements are correct regarding the geologic time scale and orogenic phases: there are multiple phases, Alpine is the most recent, and the listed mountain ranges are correctly categorized by their respective orogenic periods.

Multiple choice

What is the role of fossils in supporting the theory of evolution?

  1. There are not enough fossils to support this theory

  2. There are plenty of fossils to show that animals have evolved, but there ar

  3. There have been many fossils of intermediate types discovered that provide

  4. show that other types of life existed, but there is no evidence of relation
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Fossils of transitional or intermediate forms provide strong evidence for evolution by showing links between groups (e.g., whale ancestors, bird-dinosaur transitions). These fossils document evolutionary changes over time.

Multiple choice

Fossil Fuels:

  1. Will Run out Eventually

  2. Are randomly spread across the world

  3. Are plants and animals buried millions of years ago

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Fossil fuels are finite (will run out), are unevenly distributed globally, and are formed from the remains of ancient plants and animals, making all the provided statements correct.

Multiple choice chemistry rocks and minerals carbon cycling mineral coal coal and its products
Coal is a sedimentary rock formed from plants that died a millions of years ago.

  1. True

  2. False

  3. Neither

  4. Either
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Coal is a sedimentary rock formed from plants that died millions of years ago.

As more and more layers of dead plants and animals got deposited on them, due to heat and pressure they changed to form coal.

Hence, option (A) is the correct answer.

Multiple choice zoology animal diversity - ii (phylum: chordata) amphibia and reptilia amphibia classifications of chordata

Living fossil lizard of New Zeal and/Sphenodon belongs to___________.

  1. Rhyncocephalia

  2. Squamata

  3. Chelonia

  4. Crocodilia
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Living fossil lizard of new zeal and sphenodon belongs to Rhyncocephalia. The single species of Tuatara is the only surmising member of its order, which flourished around 200 million years ago.

Multiple choice zoology animal diversity - ii (phylum: chordata) amphibia and reptilia amphibia classifications of chordata

The extinct reptiles without temporal fossae belong to ______________.

  1. Chelonia

  2. Synaptosauria

  3. Ichthyopterygia

  4. Cotylosauria
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Cotylosauria, often called stem reptiles, are the most primitive reptiles and are characterized by an anapsid skull, meaning they lack temporal fossae. Chelonia (turtles) also have anapsid skulls, but Cotylosauria is the broader ancestral group typically associated with this definition in evolutionary biology contexts.
