WRITTEN WORK 4

The Himalayan Mountains are located along a portion of the Southern boundary of the Eurasian plate. At the top of Mt Everest, climbers have found fossilized marine shells in the surface bedrock. From this observation, which statement is the best inferred about the origin of the Himalayan Mountains?

• The Himalayan Mountains formed at convergent boundary.

• The Himalayan Mountains were no volcanic activity.

• The sea level has been lowered since the shells were fossilized.

• The bedrock containing the fossil shells is part of the uplifted seafloor.

Coal beds were formed from the compaction and decomposition of swamp plants that exist in the earth and possible location is in Antartica. It leads to the idea that _________________.

• A.   Antarctica was once had a cold climate

• Antarctica covered by an ice sheet.

• Antarctica   experienced a tropical climate.

• Antarctica could not sustain substantial amount of life

Which of the following evidence proved that igneous materials found along oceanic ridges contains magnetic iron particles that show reversal of magnetic orientation?

•   Earths has a magnetic field.

• Earth’s magnetic poles have exchanged position

•   Igneous materials are always formed beneath the volcanoes.

• A.   Igneous materials are always formed beneath the volcanoes.

1.   Remains of Mesosaurus is solely found in Southern Africa and Eastern South America, if the continents were in still their present positions, there is no possibility that the Mesosaurus would have the capability to swim across large body of ocean as the Atlantic because ________________.

• It was a wild animal

• It lived in freshwater lakes and ponds.

• It was a coastal animal.

• It was a crocodile - like reptile animal.

Youngest oceanic crust is found at the Mid-Ocean Ridge. Age gets progressively older as you get farther from the mid-ocean ridge. Why is the Earth not expanding in size?

• The older ocean crust is weathered and eroded away.

• The older crust is being recycled at subduction zones

• The Earth’s mass has remained constant.

• The mid ocean ridge is becoming so large that it is consuming the older the crust.

What evidence proved that South America, Africa India and Australia were once covered by glaciers?

• Cold climates

• Leftover portions of glaciers

• Enormous valleys formed by glaciers

• Glacial deposits and rock surfaces scarred by glaciers.

Which of the following statements best explain the Earth’s magnetic pole?

•    the Earth's magnetic poles are aligned with the Earth's rotation axis

• the Earth's magnetic poles are inclined approximately 11 degrees the Earth's rotation axis.

• the Earth's magnetic poles has been slowly changing throughout its existence

• the Earth's magnetic poles have happened throughout Earth’s history

When the continents of the southern hemisphere are re-assembled into the single land mass of Gondwanaland, the distribution of these four fossil types could be?

• separated patterns of distribution across continental boundaries.

• apart from the patterns of distribution across continental         boundaries.

• along circled patterns of distribution across continental boundaries.

• linear and continuous patterns of distribution across continental boundaries.

How the mid-ocean ridge increases with distance?

• the age, density, and thickness of oceanic lithosphere.

• the magnetism of mid-ocean ridges.

• the spreading in Earth’s lithosphere.

• the volcanic activity occurs along the mid-ocean ridge.

What are the important features of a glossopteris?

• It provide important evidence for distribution of continental plates.

• It is occurred in a variety of growth forms.

• It is a woody, seed-bearing shrub or tree, named after the Greek description of ‘tongue’ – a description of the shape of the leaves.

• It is found in the Southern Continents.
