All of the following observations seem to indicate movement of the plates EXCEPT—
Rifting of the ocean floor
Tidal movement
Shape of continents
Fossil evidence
An object will continue moving in a straight line unless it is acted on by an unbalanced force. Which of the following best explains Earth’s motion?
There is no unbalanced force acting on Earth because space is empty and nothing touches Earth.
The gravitational force pulling Earth toward the sun is equal and opposite to the force pulling the sun toward Earth, so there is no unbalanced force acting on Earth.
The sun moves in an elliptical orbit around Earth, and the sun’s gravity pulls Earth along.
Earth moves in an elliptical orbit around the sun because the gravitational force of the sun attracts Earth.
The diagram below models Mercury and Venus orbiting the sun. ----- What force causes Venus to travel along a curved path instead of moving in a straight line as indicated by the dashed line in the diagram?
Electromagnetic attraction between the sun and Venus
Gravitational attraction between the sun and Venus
Electromagnetic attraction between Mercury and Venus
Gravitational attraction between Mercury and Venus
On July 4, 1776, the American colonies declared their independence. The table shows the lunar phases for June 1776. ---- What lunar phase occurred on July 4, 1776?
Waning gibbous
Waxing gibbous
Waning crescent
Waxing crescent
Quasars are extremely distant celestial bodies. Investigators using a special telescope determined that a certain quasar was emitting waves with a frequency of 1.41×10^9 Hz. An electromagnetic spectrum is shown. --- The investigators were most likely using a telescope that detects —
Microwaves
Visible light
X-rays
Gamma rays
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.
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.
In the early 1900s, Alfred Wegener hypothesized that the continents once were joined together in a supercontinent. He thought that the continents broke apart and gradually drifted away from each other. What features most likely formed between the continents as mantle convection pushed the continents apart?
Rift Valleys
Subduction trenches
Transform
Volcanic hot spots
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.
Assuming that Seaview Highway is at sea level, what is the elevation of the school labeled S in the topographic map above?
2 m
10 m
20 m
40 m
