Relief

The Earth's structure is composed by several layers, every one of them is made of different materials. The Earth has three main layers: the crust, the mantle and the tectonic layer. True. False.

Semi-solid rock below the Earth's surface is called... Magma. Core. Crus. Fault.

The core is the deepest layer. It represents more than 60% of the Earth's mass and it has two parts. True. False.

It's the outer layer of the Earth. It's the thinnies layer and represents only 1% of the Earth's mass. This layer is called... Mantle. Core. Crust. Tectonic Plate.

The mantle is mostly magma and its average temprerature is around 3.000 ºC. True. False.

We often refer to the crust and upper mantle of the Earth as the... Stratosphere. Lithosphere. Atmosphere. Biosphere.

The lithosphere is a continuous layer that covers the whole plantet. True. False.

Subduction is produced by a... Divergent plate boundary. Transform plate boundary. Convergent plate boundary. Ridges plate boundary.

In their movement, tectonic plates interact with each other at the... Plate boundaries. Mid-oceanic ridges. Faults. Subduction.

Slow movement of the continents on the mantle is called... Plate boundaries. Continental drift. Faults. Convection currents.

The movement of the tectonic plates causes... Magma. Orogenic forces. Shaping relief. Gravity forces.

Orogenic forces produce the Earth's shaping relief and cause the formation of landforms such as mountain ranges. True. False.

Water, wind, temperature, plants, animals and humans are all examples of ... that shape relief. Orogenic Forces. External Forces. Volcano Forces. Inner core Forces.

The water shaping relief effect that creates landforms such as caves and sinkholes is called... Fluvial relief. Aeolian relief. Oceanic relief. Karst relief.

Changes in temperatures can cause rock to fracture because it contracts with the heat and expands with the cold. True. False.

A large, flat elevated area of land is called... Plain. Depression. Plateau. Marsh.

Mountain range is a line of high mountains. True. False.

A low area of land between two points of higher ground, such as between two mountains is called... Valley. Hill. Depression. Plain.

Depression is a large area of high land. True. False.

Mountains naturally formed sharp elevation of Earth's surface with steep... sinkholes. slopes. hotspots. dunes.

A large, flat area of land is called... Plateau. Valley. Hill. Plain.

A naturally formed elevation of Earth's surface with less steep slopes, lower than a mountain is called... Mountain range. Mountain. Hill. Valley.

Oceanic relief is the landforms that are under the sea or ocean. True. False.

An area of land that sticks out into the sea with a thin strip of land connecting it to the mainland is called... Cape. Marsh. Peninsula. Estuary.

The part that links a penninsula with the continental land is called... Cape. Isthmus. Cove. Hill.

An area where the see cuts into the coastline is called... Bay. Marsh. Delta. Cape.

A gulf is a large... Island. Penninsula. Bay. Delta.

An archipelago is a group of... Islands. Mountains. Rivers. Hills.

A small bay is called... Delta. Estuary. Cove. Gulf.

A low-lying area of land that's often flooded by the sea is called... Marsh. Delta. Island. Bay.

A delta is an area at the origin of a river, where the river deposits a large amount of sediment. True. False.

An area at the mouth of a large river, where fresh water and salt water mix is called... Bay. Delta. Estuary. Marsh.

An island is a land completely surrounded by... lava. mountains. sea. valleys.

An area of land, usually a high point, that extends into a body of water is called... Cape. Peninsula. Bay. Plain.

Tsunamis are huge waves created by... under-ocean earthquakes. volcanos. tornados. cyclones.

When an earthquake happens, how is the point of its origin called?. Tsunami. Hypocentre. Epicentre. Crater.

The point on the Earth's surface thats directly above the hypocentre is called... Epicentre. Cone. Crater. Chamber.
