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.

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.

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.
