Worksheet time: 5mins
This topographic map represents the elevation of an area 100 years ago. At that time the highest point had an elevation of 214 m. The highest point has since eroded a total of 7 m. ---- Which profile most likely represents the landscape today?
Which statement does NOT describe subduction zones?
Old crust is recycled into Earth’s mantle
Most earthquakes and volcanoes occur at these boundaries
Mountain building occurs at these boundaries
New Crust forms by seafloor spreading
Seafloor spreading causes the continents of South American and Africa to move farther apart each year. What type of plate boundary causes this crustal feature?
Subduction zone
Transform boundary
Convergent boundary
Divergent boundary
What evidence do scientists have to substantiate the fact that Earth is broken into moving plates?
The erosion caused by a moving glacier
The Stable positions of the continents
The creation of new ocean water on Earth
The creation of new landforms, such as mountains, on Earth
Which statement is not evidence of the plate tectonic theory?
Fossils of the same animals are found on different continents.
The continents fit together like pieces of a puzzle.
Similar weather patterns exist on different continents.
Mountain chains line up along the edges of continents.
Which description does NOT explain a characteristic of the Sun?
The Sun is one of billions of stars in the Milky way
The Sun is the closest star to Earth
The Sun is the only star in our galaxy
The Sun is located near the edge of disc-shaped galaxy
The table below shows the distance between Earth and seven relatively nearby stars in the galaxy. --- According to the table, the Sun is —
millions of times closer to Earth than any of the other stars.
about as close to Earth as the other stars.
thousands of times farther from Earth than any of the other stars.
hundreds of thousands of times closer to Earth than any of the other stars.
Which of the following statements is not supported
by the plate tectonic theory?
Continents move through the seafloor crust.
Locations of volcanoes and earthquakes can be explained.
Seafloor spreading provides evidence to support the plate tectonic theory.
There are three different types of plate boundaries associated with the direction of plate movement.
In 1915, German scientist Alfred Wegener proposed the theory of continental drift. Wegener found that continents were slowly drifting around the surface of Earth. Later scientists were able to explain the processes that drive continental drift by looking at the phenomenon of —
Seafloor spreading
The origin of Life
Global warming
Radiocarbon dating
The term “seafloor spreading” is best used to describe –
the submergence of the Pacific plate beneath the North American plate.
the rapid drop off between the continental shelf and the abyssal plain.
the tsunami effect associated with the eruption of underwater volcanoes.
magma upwelling and lateral expansion along the mid-Atlantic ridge.
