The early hypothesis of ___ was based on observations that suggested continents were once join together, Later, the theory of ___ explained why large pieces of Earth's surface move around and how many of Earth's feathers form.

In the Earth's mantle, heat is transferred in large convection currents. Within these currents;

Which of the following statements is true?

Most of the energy in Earth's atmosphere, oceans and living systems comes from ______.

Layers of sand and other sediment that become sediment rock

At divergent boundaries plates move apart, magma rises upward between them and erupts onto the ocean floor as lava. This lava cools quickly to form solid rock. Over time, these hardened lava flows build up on top of each other and are uplifted by tectonic forces to form mid ocean ridges.

Based on this information, what type of rock are mid-ocean ridges made up?

Which of the following lists Earth's compositional layers starting with Earth's center and ending with the outermost layer.

Which shows the steps of the formation of sedimentary rock in the correct order.

How do volcanic mountains form?

The images show how Earth's continents looked 250 million years ago and how they look today. The change in the continents' positions is explained by the modern theory of plate tectonics.

The theory of plate tectonics developed in part from an earlier hypothesis about how continents move. What is the name of this earlier hypothesis?

The Earth's surface is divided up into several large movable tectonic plates. Which of the following is true about these plates?

Many people have a tendency to think that heat and temperature are the same thing. However, this is not true. Heat describes:

Due to its ability to camouflage itself from predators, the White Peppered Moth of England was once much more abundant than the Black Peppered Moth. As the Industrial Revolution hit, factories began to release black soot which coated everything including tree bark. Because the moth's habitat was now darker, the white moth became much more susceptible to predators at the same time, the Black Peppered Moth was now more protected and began to increase in number.

This story is an example of:

Some rocks are pushed deeper into the Earth, As these rocks experience greater heat and pressure, what type of rock will they turn into if they do not melt?

What are the 2 main factors in the mantle that contribute to the rock cycle?

Before the present theory of plate tectonics, scientists used the hypothesis of continental drift to propose that Earth's continents are in motion. Which of the following were initially used to support the hypothesis of continental drift?

I. the matching shapes of continents edges

II. similar fossils on different continents

III. matching rock types on different continents

IV. evidence in the rock record for climate change

Faults are:

A cell divides to form 2 cells during a process called

What is the name for the process of recycling materials that make up the Earth's crust and mantle?

Which choice correctly completes the sentence?

___ reaches the Earth's surface through ___, then turns into ____.

Most tectonic plates move at rates of

Which statement is true?

What type of rock contains minerals arranged in crystals and forms when molten rock cools and turns solid?

Folding of rock layers occurs where pieces of the Earth's crust
