Lesson 1
The top layer of the Earth is called the
CRUST
The round opening through which magma reaches the surface of the Earth is called the
VENT
Mountains can form when plates
COLLIDE
The point inside the Earth where rock first moves, starting the earthquake is called the
FOCUS
LESSON 1
Plates move in 3 different ways:
THEY COLLIDE, MOVE APART AND SLIDE PAST EACH OTHER
The layer of the Earth that surrounds the core is called the
MANTLE
Small volcano with steep sides and explosive eruptions made of ash and rocks is called a
CINDER CONE
Bending of rock layers that are squeezed together is called
FOLDING
The shaking of the Earth's crust is called an
EARTHQUAKE
LESSON 1
Large section of the Earth's crust that moves is called
PLATE
The solid molten layer at the center of the Earth is called the
CORE
A mountain that develops where magma erupts onto the Earth's surface is called a
VOLCANO
A break in the Earth's crust along which movement occurs is called a
FAULT
The point on the Earth's surface directly over the focus of an earthquake is called the
EPICENTER
LESSON 4
Large sea wave caused by vibrations on the Earth is called a
TSUNAMI
Single landmasses from which the continents separated was called
PANGAEA
A volcano with a wide crater, developing from layers of lava is called a
SHIELD VOLCANO
How many types of faults are there?
The instrument that detects and records earthquake waves is called a
SEISMOGRAPH
LESSON 1
The theory that the Earth's surface is made up of large sections that move is called
PLATE TECTONCIS
The Earth is made up of 3 main layers they are-
CORE, MANTLE, AND CRUST
A tall volcano formed from eruptions of ash and rock followed by quiet lava flow is called a
COMPOSITE VOLCANO
The scale used to measure the strength of an earthquake is called the
RICHTER SCALE
LESSON 4
TRUE or FALSE
Earthquakes on the ocean floor can trigger tsunamis.
TRUE
